I wonder if it’s possible to just stay up in the air and wait for it the spin to your destination 😂
That's a real question
That's kinda what space shuttle does. Not exactly, but yes somehow.
Airplne is like a bicycle it will fall without moving., helicopter yes it can float without moving forward
Airplne is like a bicycle it will fall without moving., helicopter yes it can float without moving forward
This is not exactly what you asked but flights from the west coast fly north then after the earth turns then fly south the Asia. Check it out.
Short Answer:
No, the movement of airplanes is not affected by the earth’s rotation, due to the fact that earth’s atmosphere rotates with the planet. Meaning that any object within the atmosphere of Earth would not move in any other way that is dependent on the earth’s rotation. This is why objects in space move in different ways in relationship to earth, whereas objects within the atmosphere of the earth move with the earth, and are unaffected by our planets rotation, or revolution around the sun.
Thank you bro 😊
and you do believe that ? brainwashing is really impressive it makes people spit nonsense without even realizing it
@@Peijo2005is the same effect if the earth 🌎 would not rotate?
How about in a moving carousel? Lay people tend to explain things they have no knowledge about just as gravity is not a law but a theory because it has yet to be proved. When you ask an idiot they will try to explain with such conviction like they are experts, but when you ask a scientist they will say "WE DON'T KNOW".
------------------------
Get a grip of yourself.
This is such bs. How are you going to say that a 747 generating 1008 kilo-Newtons of force in the air for 7 hours isn't counter acting the spin of the Earth at all ( 2:24 ). So please explain how many kN would you need to actually leave the inertial frame of the earths rotation? If you say it's impossible again, then the Earth is flat and stationary.
The rotation of The Earth is not a factor. The Velocity through the air over land is.
@@captricharddee3634 Can you explain why I’m genuinely curious in the science behind this
Eotvos Effect will reduce the weight of the airplane by about 1% when flying to the east. And likely increase the weight by a similar amount when flying west. So they might save a little fuel and fly just a bit faster when heading east. But the prevailing winds are what governs the speed and efficiency of airplanes.
Einstein. The plane is moving relative to the Earth's motion.
Look. If you're on a very long train going a constant speed and have the objective to move along that train, does the speed of the train impact how fast you walk realtive to the ground of that train? No, because that's only influenced by your own speed within this inertial frame of reference. The situation you're talking about would be to counter the speed of the train, making yourself stationary relative to the outside. Assuming the train is going 200km/h relative to the outside ground, you would therefore have to move negative 200km/h relative to that ground in order to be perfectly still relative to the outside. But in doing so, you will have to move 200km/h in one direction on the train. While yes, you are now still relative to the outside, you would now be running 200km/h inside the train. When applied to the example of earth, the rotation is the speed of the train. It would not matter how fast you moved in either direction, because relative to the earth's surface it would be the same speed in either direction. Only when looking at it from the outside and either adding or subtracting the velocities, depending in which direction you go, could you "counter" the spin. But this wouldn't mean you're stationary on earth. And it wouldn't matter, as you're probably not looking at earth from the outside anyways.
The simple answer to the question is aircrafts are much much smaller in comparison to the earth itself, therefore the gravitational field of earth is responsible for this effect. In other words everything present in this world is glued to the surface due to its gravitational pull and we rotate along with the earth without noticing any angular acceleration caused by the rotation of the earth.
BS.
Gravity is not a pull it's a push space time pushes you down
Voodoo science. Never proven, mere words.
Speak for yourself buddy.
something makes me dizzy most of the time. If it isn’t the earths rotation it must be the tides sloshing around. Or maybe its the moon or sun zooming by.
Please explain how can returning space ships catch up with the earth again while it is rotating around itself and the fast running sun which is rotating around the milkyway?? Simple the earth is stationary.
Spaceships never escape the Earth's gravitational field
So pretty much the atmosphere is moving the same speed as the ground so you don't feel any difference
Nasa: Flights over a "flat, non-rotating earth with a stationary atmosphere."
We only detect change in acceleration. That planet is rotating at the same speed. Much like cruise control on the highway you don't feel leaning forward or backward unless your speed changes.
That's nonsense.
This proves something other than a spinning ball
@@JLar-bb5hlwtf are you talking about where's your source there bub
As a former Army artillery fire direction specialist, one of the factors that ALWAYS had to be factored in for calculating where the round was SUPPOSED to land was...rotation of the earth. Fire for effect! 💥💥💥😄
By what factor do you have to increase/decrease the projectile speed from east to west and west to east?
BS … if it doesn’t affect something that high in the sky, it doesn’t affect artillery. The adjustment is for wind shear and altitude difference, same as firing any long range rifle
@@s21killah do you fire rifles ?
@@s21killahdo you fire artillery?
do you get free shots as a part of your compensation package?
Spherical earth?
yeah sure.
Go ahead and use your skepticism as a valid argument.
Wow, very strong argument indeed, you should be a lawyer.
😂
Correct, it is not a sphere. It’s an oblate spheroid..
Yeah, but what if the plane is moving north or south. It is going 1600km/h at the equator, but what happens to that speed when it's over the pole?
Does this make sense: "Air planes have a gravitational pull in the direction of the center of the earth, and the only way to move in any direction, east/west/north/south is by the thrust of the jets."
If it is going at 1600 in the equator, it will still be going 1600 at the North Pole, given it has enough fuel to go supersonic for that long.
Either way it's not gonna teleport over there, the flight could take 10 hours and so it would have 10 hours to adjust to the wind speed
It's a flat stationary plane.
it does not matter. He just states that the speed is not the same all around the globe. If you move your arm it moves altogether but the tip moves faster than the base
I ask that question too. A pendulum will spin in a full circle even though stationary.
If I'm understanding this correctly the Earth's rotation affects the behaviour and speed of the plane at takeoff so surely if you're taking of in the opposite direction to that of the rotation then that should have a negative affect should it not?
No, you fly with your speed of x km/h -1,600km/h but the earth still rotates in your direction with 1,600 km/h. Thus your speed is:
x - 1,600 + 1,600
For a start in the direction of earth's rotation it is:
x + 1,600 - 1,600
There's no effect. Imagine yourself in a train which is running at a constant speed. When you get up from your seat for something, do you experience any effect? No, you don't unless.. the train accelerates or de-accelerates.. right? That's because you and train are a single system together. You will have the same speed w.r.t to the ground as that of the train. The portion of the earth that the plane is standing on is also moving with a constant speed w.r.t to the centre of the earth. So, if the plane tries to take off in whichever direction, it will not experience any effect for its relative speed with the earth is '0'.
PS: The term 'acceleration' that I'm referring to here, purely, means the rate of change of speed and not velocity.
simple answer : there is no rotation
You wish.
Evidence says no.
I'm also confused, let's assume if i get up in the air staying at constant spot for at least one hour, and as it stated that the earth is rotating at the speed of 1670 km/h, now, when get down, why do my position remains same and not changed?
@@sherkhan3139because when you started you were moving at the same speed as the rotation of the earth. This is explained in the video.
@@efoxxok7478then why air moves in different directions
Theres more to this topic. Flying westward 1600kph at the equator eliminates the centripetal momentum, therefore objects will weigh marginally heavier. But if eastward, it will be marginally lighter, and so the same propelling force allows objects of the same mass travelling east, to fly marginally quicker and higher. And higher further reduces the gravitational pull by another tiny margin. At altitude where air mass is so thin, aircrafts can and must travel quicker to generate enough lift against its weight (not mass).
For anyone interested in this topic, it's called the Eötvös effect.
This is a VERY interesting point! I was never condescending this! Now, the entire story about air planes flying west or east raises more and more questions!!!!!! Thank you!
@@edlauren9434is there an effect on the fuel consumption?
@@GuardianSoulkeeperfirst time I heard about it
I think we all need to remember:
The earth is rotating at 1600 kilometers per hour,
1-And the air nearest the ground is also traveling that speed.
2- also you and I and the parked airplane are also traveling at the same speed while we are “standing still” on the earth.
But yes this video has my mind doing a lot of thinking.
NASA's *_"Conservation of Momentum"_* (look it up) explanation does not work for a plane north or South bound departing from the equator rotating @ 1600 km/hr. flying to one of the tropics rotating 1000 km/ hr. Nor will NASA address this discrepancy.
I think it does matters.When the plane goes with the direction of the earth,the plane receives more centrifugal forces what makes the plane a little bit lighter .And a reduced weight makes the plane faster.
Why did that make absolutely no fucking sense?
Made perfect sense to me.
that's due to the relative nature of sense.
Because he didn't mention relativity...
So what stops the earth turning under the planes? Why does he say it doesn't matter if you're flying east or west you go at the same speed then says you go faster east cuz of the earth turning? So the earth pulls everything along with it except for air? How come even from the moon or from Mars you can't see he earth turn? If when you jump in the air you'd wind up hundreds of meters away if it wasn't for gravity so why can't you see that rotation from space? If you had a steel ball spinning in a circle and had magnets attached to it and you flicked the magnets up in the air off the ball they'd come back down to the ball but not in the same spot they left from so how does gravity work differently. How can you have people on the top, sides, and bottom of a ball obviously standing upside down compared to each other but they all think they're standing upright on top of it? How does gravity change your perception of standing upside down on the bottom of the ball? Why can't we replicate this effect of things sticking to the ball even though it's spinning? Things fly off a spinning ball. How does the ocean water curve curve upwards to form a ball? Water always flows to the lowest point so how does it also hump up in the air forming a ball? If gravity is constantly pulling everything towards the center of the earth why isn't all the water underground? How does water flow upwards in rivers when they're on the side of the ball as it's rotating? Why does water flow downhill off mountains but then stop when it gets to a certain height and not continue it's downward path underground? If the gravity is pulling the water down so hard it forms grooves and canyons on the earth why doesn't it pull the water underground? How does we have tunnel systems all over the world that arent filled with water? Ever seen the show about the money pit with all the traps that flood the tunnel so they can't get down there? Why doesn't all the water do that and flood all tunnels everywhere? Still a whole lot makes no sense...
There must be a big lie somehow?
Sorry but it's not flat there lil buddy
🤔 I agree with you
If you spend 24h on the moon and you look all the time towards the earth you will certainly see all the continents passing by in those 24h. But you will certainly not see Africa, Australia and South America at the same time. Impossible!
the video got me when finally someone knew how long it takes the Earth to rotate around its own axis.
Waiting for someone to say the moon doesn't rotate on it's axis. So many people think it doesn't.
I think this has been known for quite some time. A very long time.
The air and the ground moving with and rotating with the Earth. When a plane is either on the ground or the air over that spot on the ground, it is moving at the same speed as Earth rotation. Like a car, if you add propulsion you will begin to move over the ground at a given speed, the same applies to an aircraft in the air, it moves thru the air and over the ground at a given speed. Now add a tail wind speed or subtract head wind speed from the ground speed and that dictates how long it will take the aircraft to arrive somewhere.
A fun experiment would be to put a drone on a merry-go-around. Start the the rotation with the drone being stationary. Get it to the speed of the go-around to x speed and then launch the drone vertically
if you jump up you will land west from the point you jump due to Coriolis effect. There is a Coriolis effect. if you jump 20cm then the effect will be only few micrometers. But if you throw a ball to a height of 20m then the effect will be few millimeters. And if you shoot a bullet to a height of 1km than the effect will be approximately few decimeters up to 1 m.
that's wrong. just saying.
The location of the bullet drop will be mostly decided by wind. It could actually land the other way.
Let's count! The earth is spinning approximately 1000 km/h on the spot where the majority of the western people lives. There is 1 million meter in 1000 km so it is 1 million meter/hour what is 277 meter per second. If you jump up 20 centimeter that is around one second.
Isn't the deflection North or South depending on which hemisphere you are in?
I'm not entirely convinced, Here's why...
Planes fly higher where there is less air for better efficiency, which also means less resistance, less resistance would make an object in motion (airplane) under its own power faster in one direction than the other.
Yeah, me too. When he mentioned newtons first law of motion, yes there is an external force that counteracts the earth's influence on you when you're up in the air, and that is air friction/drag. You have to be in a vacuum for that law to be applicable. Also, the coriolis effect is real.
@@kurtdy6489 Correct. The fact that the Earth's spin doesn't affect the plane's speed is because the plane is moving relative to the Earth's motion, whether that be its spin or journey around the sun. Einstein, more so than Newton, is your friend here and our host has confused the issue and ruined the whole premise.
Not really. If less air can make airplane faster, it would benefit both.
@@kurtdy6489, the friction wants you to stay still relative to the air. Air tolerates friction from the Earth surface and no force from the space. So it can only move in sync with the Earth, therefore the air friction wants the plane to rotate in sync with the Earth.
The air friction is the same no matter what direction you move.
“Less resistance would make an object in motion move faster in one direction than the other”
Less resistance only makes object move faster in all directions. Plane experiences no force from the space, so why should it care how the space rotates relative to the Earth?
The fact that jet steams are eastward rather than westward, are indeed due to earth rotation.
@pyropulseIXXII too would like to see the proof and the equation of motion of those jet streams
Moving air, water is deflected to the right in the Northern Hemisphere by the Coriolis effect, left in SH. These effects are large over big distances. But the effect would be the same whether you’re flying east or west. Except-if you’re headed East, you’re deflected in the direction of a faster spinning planet-in the NH.
Coriolis is an APARENT force meaning it does not do anything , only appears to deviate.
Yes, earth rotation does not matter for planes but what about the satellites which are placed at heights above the air zone of the earth?
You mean those ballons?
Nice try@@radicaIarchitect
They orbit the Earth, their velocity is much higher than the ground's
It's an interesting quirk of orbital mechanics. The satellite itself follows a path on an orbital plane whose orientation essentially does not change. The reason the satellite doesn't simply track over the same part of the Earth over and over is because the Earth is rotating.
That's why with each orbital "cycle" (in LEO each cycle is roughly 90 minutes) you see the path appears to shift westward by 22.5°.
Looking at the comments here, it seems that by mentioning Newton and not mentioning Einstein, you've confused the issue. Let me say in one sentence what you took 3:15 to say, but never actually said. The answer to to whether the Earth's rotation affects the the airplane's speed or flight time is 'NO' because the plane's movement is relative to the Earth's movement, whether that be the Earth's spin (approx. 1,670km/h or 1,000mp/h or its orbit around the sun (approx. 107,000km/h or 67,000mp/h).
Wait how does the air move ? What force does this?
It doesn't move. Niether does earth.
The uneven heating of the earth's surface from the sun
Convection ?
When you lie it can be hard to keep track of them . Why are we told the motion of the Earth effects ballistics (Coriolis effect ), but not air travel ?
because planes are constantly adjusting their course due to wind.. and that adjustment is more than would be needed to adjust for the Coriolis.
by whom are we lied to? those two are two totally independent things; one's affected by the Coriolis effect, this the other isn't. therefore it's pointless what you said.
Because these are two completely different things. You're talking about the "Coriolis force", not the "Coriolis effect". The Coriolis force effects rotating objects, which is why a bullet fired from an unrifled gun (NON rotating bullet) behaves differently to a bullet fired from a rifled gun (ROTATING bullet - here, try this: en.wikipedia.org/wiki/Coriolis_force), while the Coriolis effect is to do with how the Earth's spin effects air currents.
For the same reason we can't have visible stars on the Moon. They told us they didn't see any star so now we can't fake a believable moon landing because we can't contradict the earlier missions. It is better just to tell the truth always. You will lose all of your "friends" but at least you will can answer without thinking about your lies.
It does affect aircraft but its not something a pilot has to specifically think about. Its effect would be like a very slight side wind, but since the wind direction is never really constant pilots can't really fell the difference. They turn the aircraft until its track over the ground is in the direction they want to go and this takes care of everything, wind, coriolis, turbulence, too many thin people on the left hand side of the plane. Everything. Ballistic objects on the other hand aren't steerable. You have to take into account everything that might affect the trajectory at launch time. In addition they are generally a lot faster which increases the coriolis effect.
00:12 Graphic shows aircraft flying E-W at the same latitude. Long range overseas flights usually take the shortest route over the northern or southern hemispheres so they fly at an ANGLE, not parallel to the earth's rotation.
Hypothetically speaking, say I go to outer space and i am outside the earths gravity field and I stay still would I see the earth rotating at 1000 mph ? If so would it be faster to travel than a normal airplane.
There is a subtlety however. Eastward flying planes are actually lighter due to the earth's rotation and westward flying planes are heavier (and everything in them). This is because they are actually suborbitally flying. The westward flying plane gets heavier (at the equator) up to about 1000 mph where it then starts to get lighter again (due to the earth's rotation). The eastward flying plane gets lighter the faster it goes. If the eastward flying plane could go 17,500 mph, it would actually weigh nothing!
Earth rotates on its access, orbits the sun, sun orbits black hole of Milky Way, galaxy shooting through the universe, four different motions in four different directions at ridiculous speeds each one, and yet? We’ve seen the same stars/constellations in the firmament for Eons, they all rotate pivoting on Polaris in ONE circular motion, NOT FOUR… how’s this posible Neal? Anyone?
Stars do change positions a bit, a few thousands years ago a different star was used to determine where North is. However it's because of Earth's precession. Other movements don't really change it. Earth's orbit isn't really significant, as stars are hundreds of light years away. Orbit around Sagittarius A doesn't change much too, because most of the stars we see orbits with us.
Well first it is not pointing directly at Polaris. Polaris still over In a small circle each night. Polaris is also moving around the Milky Way so it even stays relative to the earth. Infact.all the stars you see also is moving just like the earth around the center of the Milky Way. The vast distances also make them seem like thru dont move.
Hint: polaris wasn't always the North star. The stars do shift relative to us. But the distances involved means it takes a while..
Your inability to understand something doesn't mean it's fake.
The atmosphere itself rotates at the same speed as the earth neither adding or subtraction to the ground speed of the aircraft other than localized winds caused by high and low pressure differentials.
The Eötvös effect reduces apparent weight for an aircraft ravelling East, reducing fuel consumption.
The airplane normal cruising speed is around 880kmh. The speed the Earth rotates is 1600kmh at the equator. what does this mean?
Viewed from the space, the plane that fly to the West will actually look still moving to the East instead of the West from a point of view in Space.
No, an aircraft is rotating with the Earth when it is on the ground and so has angular momentum. It does not magically lose this angular momentum when it takes to the air. Conservation of momentum is a thing. Take care.
The earth is moving at 1600kmh plane is moving at 2480kmh an hour
No it doesn't. A plane moves with the wind and the wind moves with the Earth. What speeds up the plane is the direction and speed of the wind. Tailwinds speed up a plane's speed over the ground. A headwind slows it down.
It's the same physics as a boat driving through a river upstream, downstream, or crosstream however you sailors call it.
I read that the 'Paris Gun" fired a shell so high that the armillary computer had to take into account the turn of the earth to calculate where the shell would come down?
Earth rotation does affects airplanes but in an indirect way. Earth rotation affects the weather and weather, mainly wind, affects airplanes
To put it simply, an airplane always flies with a speed relative to the air, for that there are the pitots. the ground speed is calculated by the navigation and gyroscopic system. it is the one indicated on the screens in the cabin. I remember passengers complaining that the plane was too slow but we had a very strong headwind but the plane was flying at cruising speed. a stewardess came to the cockpit and asked the captain to explain this to the passengers. of course the flight time was greatly increased compared to normal. on the other hand, on the return with a very strong tailwind, the flight time was greatly reduced compared to normal.
so lets say if galactus was to visit earth and if he were to watch us from space we would pass him at 1600 kmph
but if hed hold out a finger all the buildings will get smashed at 1600 kmph on hitting his finger
Are the ocean levels the same on both sides of Panama?
No
The only thing was that, in the animation, the two planes flying in opposite directions around the globe appeared to be flying at the same speed relative TO US and not to the rotating earth sirface.
But when it takes off then turns 180° how is it doing 1,600 kph in the direction it originally went in?
Ever hear of Einstein
Because everything is in the same motion you can qualify earth movement at 0. No force changing your flight path or velocity
It's only 1600 kph when stopped
It's because the earth is a flat stationary plane. Not a spinning sphere
Because everything it is contained in ie the earth and its atmosphere is moving in the same direction and speed. You need to exit the atmosphere and go to space to make use of the earths rotation.
the confusing part is that even THIN AIR AT THE TOP is moving with the same force and speed??? the higher up you go, to the extremes, is where I am still puzzled and looking for answers. I guess that it makes sense that (a better example would be a paper air plane throw inside a train... which is just a mind boggling reminder that we are in space moving at crazy speeds, yet we think of it as EARTH moving at that speeds but its us too
Our frictional atmosphere extends to altitude of 300 miles. Space stats at 60 miles
This is very informative and educational.😎👍
Its simple, earth is flat and not rotating
If the Earth is flat as you claim then where do you think the Sun goes at night?
Good lord, enlighten yourself, and watch a spacex launch.
I think it all comes to gravity. As long as something is affected by gravity it will basically stay anchored to that point even in the air; this is just a hypothesis of course but I think about helicopters that can hover over the same spot for hours if they need to and the earth doesn't fly pass it ; even with winds it will stay relative to the point is hovering over .
So I think anything under our atmosphere will stay in the same motion relative to the earth until we escape earth's gravity in space and then we can see the earth move under us.
It's not gravity; it's momentum.
I am also thinking the same since I have began to think of this matter.
I am also thinking the same since I have began to think of this matter.
This is correct, but it's much more fun to hear all the flat earthers who are completely ignorant of all physical reality plead their case.
No if there is wind, a helicopter hovering would be pushed by the wind. The pilot counteracts the wind with the flight controls so the helicopter stays in that spot relative to the earth's surface.
So you are saying, a wall of atmosphere traveling at 1600kmph has ZERO effect on a plane fighting that atmosphere going east...my dear sherlock, you explained nothing, earth is flat.
You do realise that the atmosphere is rotating with the Earth? You do realise that a plane in flight still retains the angular momentum that it had on the ground? You do realise that if the Earth was "flat" as you claim the the Sun would always be visible?
You know nothing
Implying a wall of vacuum is traveling just in front of it.
Makes sense.
So the simple answer is 'yes', the earth's rotation affects flight time because of the jet winds making eastbound flights shorter than westbound flights.
Does Earth's Rotation affect the Airplanes Speed & Flight Time nope but wind direction does so 😛😛
Thanks, I have pondered bout that particular thing. Thanks!
Newton invented “gravity” in 1666
No, he was experimenting on it in 1665
“Proposed the theory of gravity” not invented. Gravity was there the whole time.
He discovered all of it's effects and correctly made mathematical formulas to explain its effects. It wasn't discovered.
The Jetstream is like green thing that can boost your speed in Crash Team Racing game or conveyor belt in mall
Crash: Woah!
What about the earth going through space at nearly 67,000 mph does not change planes speed or flight duration ?
Have you ever heard about frame of reference?
no because the earth is geocentric ......
air plane
in the air above the Plane
PLANE T
No.🤦🏼♂️
It is a very interesting and informative video. Thank you. 👍
Maybe the Earth is standing still. There are only the wind flows that influence the aircrafts movement. That would explain without any doubt why, given no winds, the airplane heading any direction reaches the endpoint within the same time. But then, what about the Sun?
There is no such thing as bring stationary. Litterally everything is moving. In a reference frame like earth's surface, there is only stationary relative to another thing like earth's surface.
yes it is still,.......there is no way to land a plane, on a surface of a ball spinning at 1600kph,.........unless you have a plane that can travel at 1600kph.
Bugs bunny disapprove it already
relative to the sun, the plane's speeds differ
If I hover above the earth at 10 meters the earth won’t move breath me (separately). If I’m in low earth orbit it does………
So……….
What height is where it all starts to change?
Earth is level
If you "hover" then you won't be in an orbit will you, as to be in orbit requires a tangential velocity. You will need to have quite a large a force acting on you to give you this velocity. Also when and object is on the Earth's surface it is rotating with the Earth and so has angular momentum. It does not magically lose this angular momentum when it leaves the Earth's surface. Take care.
A bullet and artillery shells are effected.
holy ur right. Something about this topic makes me really dizzy to be honest.
So if sniper bullets get affected by wind and earth rotation, same for artillerry shells, then there must also have to be some effect on an airplane,
that travels for 12 hours, right?
I dont really know, but this whole topic feels like some questions and answers are still open for discussion.
I would really like to know numbers on how much the effect is on planes, and if it gets bigger or smaller depending on the size of the plane.
"it does not matter wheteher an airplane is moving westward or eastward, it is always moving at the same speed, TO THE EARTH"
okay my question is this, if the speed we maintain when flying a plane is always similar, when compared to the GROUND, doesn't that suggest airplanes moving eastward with the earth are needed to exert a lot more force to not only keep up with the earth's rotation, but surpass it at the same relative speed of an airplane going the opposite direction?
I researched, and planes move at about ~800 km/h. meaning half of the earth's rotation speed. for the speed to be maintained (relative to the earth) when flying eastward, shouldn't the plane exert 3 times its engine force?
also, in the video he mentioned jetstreams, saying "moving in the direction of winds saves fuel and time" which confused me even more. the atmosphere always rotates with the earth and it moves at about the same speed. so moving "in the direction of the wind" is always moving eastward, with earth's rotation. does that mean the wind is powerful enough to "carry" the airplane with it, so that we actually need to exert LESS force to fly at the same relative speed to the earth (when moving eastward that is)?
please, I'm losing my mind over these questions. if anyone knows the answers I'll be eternally grateful
Flying from Bangkok to London takes 13 hours. Because plane is flying into the jet stream wind.
Flying from London to BKK is shorter hours as plane is pushed by the wind.
Same as if your on a train with a toy helicopter. When the train takes off the toy helicopter wont hit the back wall. An a car going 60mph if you dont have a seatbelt on an crash you are flying 60mph
A train has a roof . Try flying it on a flat bed then tell us about it
@@nickmerix2900That's because of the wind. He's right. In a vehicle going at constant speed ( not accelerating or decelerating), the toy will travel along as if it's inside a house. No difference. The train is the earth in this example. Wind will of course affect the flight in both cases, earth and vehicle.
Think of this also. Even though the earth is rotating fast all the time, why is there no wind on certain days?
@@nickmerix2900 Once again, it's relative. The toy moves relative to the train when it's inside the train, outside the train, not so much. See Einstein's first thought experiment on the speed of light (travelling in a train at the speed of light through a station and what you'd see compared to what the people waiting on the platform would see.)
@@nickmerix2900 then that’s the air or wind friction that comes into picture. That’s exactly what this video is talking about. The wind will determine which way is faster.
Yup! The plane's travel time is affected by the rotations of the Earth. When the plane move along the wirh the rotation of the Earth, it tàkes a bit longer to reach the destination. But if the plane travels opposite to the rotation direction of the Earth, the plane reaches the destination earlier compared with the first one. One more thing to consider is, when the plane's altitude is higher than usual, the plane should travel faster to reach the destination on time.
Of Course it does
Thank you, that was very convincing, you should be a lawyer.
Tell us why
Wait a minute, at the equator the earth rotates at 1600km/ph take off speed of jetliners range from 240-280km/ph now, if we built airports at the equator, does it mean all jetliners will take off at the same speed the earth rotates at, if the earth rotates with everything on it at the same speed? The same question when it comes to landing, how much runway would be required at the equator for a plane landing at equivalent speed with the earth rotation? What would be the breaking intensity applied to stop that object?
Why would going the same speed as the ground get you anywhere? Do you mean doubling the speed?
Did you even watch the video? No it wouldn’t, in case you were wondering.
Ok I'm confused
A direct flight from Islamabad moving towards Beijing requires 5 hours to reach
While the same route requires almost 6 hours travelling from Beijing to Islamabad
Why is that?
I always wondered why when i fly from Germany to the US its about 10 hours and back its 9 hours.
It all depends on the Jetstream, headwinds/tailwinds, and the speed of the aircraft.
Jet stream. Air movement is causing the difference. Did you even watch this 3?
The earth doesnt rotate proven a trillion times over
What about the flight North-South (or vice-versa for that matter)...?
Bob Segers song, against the wind......yes its true.
We are moving along the atmosphere....atmosphere moving along the earth ...glued together... one very interesting fact...we never touch a point again in space though the earth is rotating ....it is the same as falling from a cliff you will never re-visit a point that you have just passed...earth rotates around the sun which is also rotating in a bigger orbit so in a sense we are rotating and also moving forward in a spiral path
Cool. Earth spins fastest in nov and slowest in April. Winter winds are affected by earths spin.
Gravity has an influence on the weight of the airplane. Therefore the "rotation" around the earth reduces weight going east, with the earth rotation, and increase weight going west, against earth rotation. Centrifugal force is this factor.
Weight, influences fuel consumption but not flight time.
At the equator the earth rotation is 1666,6 kmh (40.000/24)
IF a plane's speed is 1666,6 kmh this dubbels the force east or "nulls" this force going west.
v^2/r= (462m/s)^2/6300000m=0,034 Newton
Therefore simplified, weight is increased by this N amount going west and decreased by this N amount going east.
Difference is thus 0,068 N
1 G is 9,8 N = thus 0,068 N is aprox 0,7% of the weight.
If this aircraft weights 100.000 kg its a difference of 700 kg at a speed of 1666,6 kmh at the equator.
Since a regular plane's speed is 850 kmh and not 1666 kmh this effect is much smaller but for the Condorde this effect was greater.
Concorde at Mach 2 the effect was aprox. 2 % thus 2000 kg in weight and therefore important in fuel consumption.
For a regular plane it's aprox. 0,01% and therefore not relevant messurable in full consumption.
When the runway is filled and the plane has to "Circle above the airport" for 20 minutes, how does an airplane moving 700 mph catch up to a runway moving 1000?
Realistically? No. Could it be measured? Yes. It is is statistically insignificant number that winds alone will erase whatever effect the rotational effect might be.
Does Earth's Rotation affect the Airplanes Speed & Flight Time - Does Earth's Rotation affect your walk eastward or westward?
NASA's *_"Conservation of Momentum"_* (look it up) explanation does not work for a plane north or South bound departing from the equator rotating @ 1600 km/hr. flying to one of the tropics rotating 1000 km/ hr. Nor will NASA address this discrepancy.
The Earth's gravity is different by regions. When a plane carries compressed matter, misiles, you can crash the plane by making earthquake at the actual region, where the plane flies.
Make a paper ball on moving train bus and throw it above and have to check if it falls to same spot or back side
I agree with AI, from ChatGPT:
In theory if I could jump and stay in the air for 10 hours, due to earth rotation, will I land in the same spot after 10 hours?
No, if you were able to stay in the air for 10 hours, you would not land in the same spot due to the rotation of the Earth. This is because while you were in the air, the Earth would continue to rotate underneath you, so when you landed, you would not be in the same place where you jumped.
The Earth rotates at a speed of approximately 1,000 miles per hour (1,600 kilometers per hour) at the equator. Therefore, after 10 hours, the Earth would have rotated by 10,000 miles (16,000 kilometers) at the equator. If you were able to jump high enough to stay in the air for 10 hours, you would still be moving with the rotation of the Earth, so you would land in a different spot than where you started.
Earth would continue to rotate and so will you, unless something will aplly force on you
You would do if you stayed off the ground and stationary to the earth’s rotation (which is not actually possible without some form of thrust to match the earth’s rotation).
If you just hovered like a helicopter does you would rotate with the earth as the atmosphere is rotating as well.
Interesting question! So, in aviation, the standard is feet are used for altitude, nautical miles for distance, and knots for airspeed.
When we do our calculations for takeoff and landing, it makes no difference what latitude we are at. A 140 knot approach speed is the same at the equator as it is in Canada.
If this mattered for takeoff and landing, it is either too small of an effect to even worry about or it is already part of the base assumptions at a very deep level that even the aviation engineers who build the charts and software we use don't care about.
Never thought of that before. Thanks!
That is completely wrong. When you jump up, your body is travelling at the same speed as the earth's rotation, so no matter how long you stay in the air you are travelling at the same speed as the earth's rotation, meaning you will land again in the same spot. That is basic physics.
Earth is flat and stable and motionless
No, it is not. FE fail every single sunset. And all the flatters do is cry about it as opposed to explaining why in mathematical detail. After all, the FE map is only 2D - simple math, bro!
The education system really failed to teach you basic physics
just like your brain
This person called kit canyon or whatever, the education system absolutely failed you. All this heliocentric teaching that they taught is such garbage. If we are flying in Cork stirrings to space billions of miles per year how is the North Star always in the same spot? Chew on that one there bud. The Earth is Flat!!!!
Look up David Weiss and his sunset video he filmed in his kitchen. That explains sunsets look it up globetard
1:52 This footage is either pretty old or the future. Because the airline went bankrupt in 2017 and Sundair bought the trademark in 2023. 😁
If the earth suddenly stopped spinning from 800 mph everything on its surface would be hurtled off its surface at 800 mph. Oceans, planes, cars, people, etc unless you were strapped done to the ground
If a plane halt its movement at the altitude of 30,000 feet for almost 12 hours or more than that then?
The comment section here has me shaking my head at the utter lack of knowledge people have about basic physics. Our youth is doomed.
If the atmosphere rotates along with the Earth how can a balloon move with respect to ground?
The other flaw of the argument is that a plane moves with respect to the atmosphere not the ground.
And there's a third problem with it: an airplane has an internal engine that makes everything different so as to "jump and wait".
I am still not convinced yet...
Your statement is not accurate. You make the assuption that the molecules of the atmosphere behave like a iron rod pinned in the ground.
That assumption causes two issues:
Firstly, the air masses above the equator will travel at 1600Km/h and the air masses above Europe (around 45 degrees North) will travel at half speed (around 800 Km/h), in order both of them to accomplish a rotation at 24h on different earth circles. This speed differential of the aerial masses should be causes trementous turmoil (the earth atmosphere would be like Jupiter), but it's not happening on the real world.
Secondly, you can't expect that as the altitude increases the molecules of the atmosphere will behave again like a solid object. Due to friction the lower layers will follow the surface linear speed but the high layers couldn't keep the same speed (actually due to increased radious from the center of the earth those molecules should have a bigger linear speed to remain aligned to surface below them).
It's far more complicated issue and needs more explanation.
Because of gravitational effects, this explanation is correct. But, the farther you are away from the surface of the earths’ surface, gravity will have less of an effect and an object will be able move quite independently with respect to the earth’s surface. Hence, satellite orbits around the poles and geostationary around the equator.
Passed you by again. How do we meet and align parallel for landing my dear.
It takes about 4 hours to fly from LA to Atlanta, it's about 2,000 miles and flight speed is around 500mph. The earth is rotating away from the direction of flight at 700 mph, so according to this video, we had a tail wind of 700 mph, which is rediculous. Did we have the same headwind flying from Atlanta to LAX? If so, the air speed would have been about 1200 mph to make the flight in 4 hours but the Boeing 747 has a max speed of 544mph, afterwhich th plane can become unstable. Just using some basic math, none of this makes sense.
When traveling eastward, the plane is actually going the speed you mentioned PLUS the speed of the earth rotation. Because even when a plane is sitting on the tarmac, it is moving at the speed of the earth.
It seems you’re missing the reference point.
The air nearest the ground is ALSO traveling at the speed of the earth. Which means the earth speed is the constant- the reference point.
@@joshuaborem7063 Then explain a 30 mph wind coming from the west.
What if a plane flies north from the equator. Say from Mexico to Alaska? It has an initial lateral velocity of 6000 km/h due to the rotation of the earth, and it flies to the north where the peripheral velocity is much lower. How will they compensate for that difference?
Most of you fools here know the truth but choose to believe in lies. At what height, does the "air" stop spinning with the earth ?? If that is true, then a plane should be able to fly up to that point and just wait it out ! Are planes adjusting their altitudes every 2 minutes in order to avoid flying off the earth ?? They dont. why would that be ????
LMAO here is another simpleton that only believes the version of reality he is able to grasp. Your ignorance is not a valid argument. "Why don't airplanes fly up to where there is no more air"??? Because maybe, just maybe, airplanes NEED air of a certain density so that the wings can produce lift? Again, go back to basics, reality if way out of your league.
LMAO you call others fools while all you have got is nothing but your juvenile skepticism? You think that airplanes would fly off into space if they don't "adjust their altitude"??? Do you even know what altitude is? Go back to the basics before embarrassing yourself like that. Friendly advice.
I bet you think you are smart After writing this. Hilarious.
Is momentum really so hard to understand?
So if I understood this correctly, an aircraft flying west cancels out some of the the rotation speed of the earth with its engines, thus letting the earth move eastward underneath at a faster speed until it reaches its destination? Whereas an aircraft travelling East ADDS to the rotational speed to reach its destination. I never thought of it this way 🤔
no, it is due to the jet stream wind patterns. Without wind, airplanes would travel the same speed relative to earth going either East or West.
earth dues not spin
It dues-n’t? 😂
Read a book
Earth is still and motionless Einstein proved this not once but twice
Nope. But how can you believe Einstein since he also claimed the earth is a sphere in a vast universe?
So if that's the case why did it feel quicker to go from NY to Seattle than going from Phoenix to NY?
Earth os flat , they dont have explication for this
Pi r squared
hey, video creator. I've to say, as a human being, that I'm highly embarrassed by the amount of highly uneducated people you managed to amass in this comment section. never before have I witnessed something like this. I'm beyond words. would that be an actual representation of mankind, we'd all be doomed.
What do you expect. All the flatheads are here..
Is there any effect of friction? I mean, as we are moving towards poles the wind speed decreases and the net result of friction should go down. Also it should be the same case with East to the West. travelling. I would be glad if someone clarifies with science & maths.
The equator doesn't go through central america. It goes through Ecuador in South America and the Congo in Africa.
