Coriolis Effect or Why You Can’t Shoot Straight
Вставка
- Опубліковано 11 лип 2024
- Earth is a spinning sphere and as such has some quirks. One of which is the apparent deflection of moving objects not attached to the ground. For example any object shot into the sky will curve to the left if flying in the southern hemisphere and right if in the northern hemisphere. This deflection is due to the rotation of our planet and is called the Coriolis Effect. The Coriolis Effect is why the Foucault Pendulum rotates clockwise in the northern hemisphere and counter clockwise in the southern hemisphere, why airplanes adjust course, and why hurricanes spin clockwise in the southern hemisphere and counter clockwise in the northern hemisphere.

There was a nice Vietnamese translation submitted by a viewer that I erased by mistake. Sorry about that. If you can reupload it, I would appreciate it very much.
Can I submit an Arabic translation?
@@omarjallad1391 Sure!
I spent 14 years in the Marines and went through Scout Sniper training school, weather its a rifle bullet, artillery, tank shells or any other projectile, we never accounted for coriolis, I've never seen the formulas for it, and in combat the spotter is not feeding the sniper corrections for it either
Underrated channel
Thanks appreciate it!
Thnx, this was a clear and easy explanation
Well, a great bowling excuse! Sounds much more credible than the magnets in the gutter excuse that I have been using for years.
very nice explanation
The east and west arent perpendicularly affected by the rotational force of the earth. If shooting east or west the bullet will not turn but hit higher or lower depending on the direction. Otherwise good example.
How does shooting directly East or west make it go left or right? Would t it just straight?

I found a brief video that discusses how the Coriolis effect might influence the apparent path of a projectile at m.ua-cam.com/video/__nTR6n0KOE/v-deo.html&pp=ygVVSGhpdyB0aGUgc3BlZWVkIG9mIG9iamVjdHMgYWZmZWN0IHRyYWplY3RvcnkgdW5kZXJnb2luZyBkZWZsZWN0aW9uIGJ5IGNvcmlvbGlzIGZvciBlcw%3D%3D on the "Stick Science" channel.

Nice animations .
I'm glad you enjoyed it!
Thanks for telling us how to make sure that bullet won't miss 😂👎
I'm joking.. Your video is really interesting 👍👍👍👍
Thanks for watching!
If I'm not mistaken when you shoot east and west no matter which hemisphere you're in it won't affect the bullet the direction of the bullet (left/right) only elevation
Correct me if I'm wrong
You're wrong the earth doesn't spin look at the problems at hand with Coriolis critically. The bullet isn't in the air long enough to be affected by the spin if a plane or helicopter isn't affected by it. All 3 leave the Earth's surface, 1 travels much faster but shorter distance's the other 2 are in flight like a bullet for hours lol seriously please think.....
@@dranopitt1202 : Where’s that proof of the magical dome?
So you claim an airplane sitting on the ground is going 0mph but the ground itself is going about 1000mph?
LOL. Seriously. Is that your claim?
Earth immovable
correct. the coriolis effect does not affect bullets. gun chamber causes bullet to spin, wide variations in wind and humidity over distance. every sniper knows the earth is flat.
@dranopitt1202
I think you're right.
A rail gun shoots a projectile at around Mach 6 (or approximately 4400 miles per hour) at a range of around 100 miles. Whereas, the earth rotates at around 1000 miles per hour. So a projectile shot from a rail gun will probably not be in the air long enough to have its trajectory significantly affected by the Coriolis effect.

Good
Thank a bunch!
But in a shot that is maximum a 1000m long, is coriollis really affecting its trajectory in a noticeable way?
From speaking to long range target shooters it begins to be noticed at about that range and has to be accounted for from then on.

Sight in your rifle scope on a range directed North-South. That’s the only way you can get correct elevation for your rifles ballistics at distance. Long range basically “starts” at 400yds. Then, when one has to shoot east or west, they can make elevation adjustments for earth’s rotation as (in the case of say a 7mm Rem) their rifle will impact 7-8” high shooting east and 4-5” low shooting west at 1000yds. Also all bullets impact a little to the right at long distance because of right hand rifling in the barrels. This is called spin drift. Now explain to me how a Boeing 737 flying 500mph can leave LA and “catch up” to NYC when it’s moving away at 500mph?
you've never shot or owned a gun. nor have you traveled in a hot air balloon at the equator
Airplanes are pulling themselves through air that is moving the same speed as the earth below (assuming no wind). There is no 1000mph wind at the equator so we know the atmosphere moves with the planet's surface.
How can I hover my drone over my head and it literally doesn’t move for hours
Because you're both moving east at the same linear speed. You're drone also may use GPS to remain at a certain spot. Coriolis is mostly for ballistic items like long range artillery fired North or South.
The flat earthers in the comments are making my day lol. It’s round, people. It’s round 🤦♀️
Best explanation for the corrolis effect on North-South / South-North shots. How ever, missed the East-West / West-East component. But it is cover here: ua-cam.com/video/jX7dcl_ERNs/v-deo.html
So next time you think you have a bad aim, blame the rotation of the earth 👍
607 views only? OMG!
Yes, this channel is very underrated.
Why do you use examples that contradict each other to explain physics? If a bullet travels faster closer to the equator then why doesnt a plane ? If a bullet misses the target north to south then how do planes land at their destination ( when the flight plan is picked before take off)? On one hand we are told the earths spin does not affect the plane because its pulled along by the atmosphere but on the other the bullet does get affected. You cant have it both ways. These presentations remind me more of infomercials than science. Im surprised by all the comments praising this video questions. I guess it takes a school drop out to point out these things and ask some questions?
The earths spin absolutely effects airplanes, but a bullet is a projectile, where as a plane is not and it’s flight path can be corrected as it travels.
@@bobbybalogne2565 if it effects planes , how is it possible for a plane flying from west to east to land on a runway oriented north to south? It would be impossible
@@nickmerix2900 the whole planet is spinning it effects everything and no it wouldn’t be impossible. Planes have controls they can be steered.
@@bobbybalogne2565 you should really think it through before you answer. The plane is traveling say 600 mph east add the 900mph it had when it took off due to earth spin. Now it needs to make a right turn to line up with the runway which is also moving 900mph . So the plane slows from 600 to 300 to start the turn . It cant just stop and turn in mid air. So now we have the plane moving at 900+ 300 and the runway moving at 900 . So how will the plane line up with the runway when its moving 300 mph faster and according to the Coriolis effect would have a side drift ? It will basically have a 45 degree vector when trying to make a 90 degree turn
@@nickmerix2900 you have a skewed understanding of physics. I could not exactly figure out what is wrong with your statement but you seem to have some misunderstandings about circular motion and the starting velocity of the airplane. Remember that the plane has a three dimensional motion. Khan academy is a great resource in learning physics and other topics, I would start there.
Moral of the story : only shoot east or west
This will effect the height of the impact. The earth will either be rotating towards or away from the projectile.

What a crock
total nonsense have you ever used a rifle
