i'm not defending that guy but the center of the earth is actually solid metal.the pressure is so high that it just can't melt those elements.That explains why we have magnetic fields.the more pressure there is ,the higher the melting point of anything gets.
Well, the weight of the earth is pretty much a meaningless number because weight is affected by gravitational attraction of other objects, so weight varies as the distance between objects changes. Mass will never change. It's essentially the "stuff" that resists a change in movement. This formula determines the overall mass of the earth. The density of each object that makes up the earth doesn't matter.
The Earth's mass is, but it's constantly weightless, well not quite, attracted to the Sun's mass, and that is attracted to some black hole in the middle of our Milky Way Galaxy, and that is intertwined between numerous other black holes.
Exponents (such as 10^24) are confusing sometimes but it's just away to simply multiplication. Take a step back and think what multiplication is. When I say 4 x 3, I mean to add "3" 4 times (3+3+3+3). You can image that if you wanted to add 3 54 times it would become very lengthy. Exponents are away of simplifying multiplication of the same numbers. For example 10^3= 10x10x10, and 10^4=10x10x10x10. It just a way to simplify writing the same number over and over again.
I agree with bubblyseal. Most people don't know the difference between mass and force (weight). People probably don't know that if the sun was the only object in space it would have no weight, because it wasn't being pulled by other objects gravitational pull
Hayden Al-Amiri. I said that wrong due to grammar errors. I was trying to say that in order to know the density of an object you have to know the mass of the object and volume. The volume is easily calculated by knowing the radius of the earth. The mass isn't immediately known. Using the method described in the video allows for the mass to be determined. Once the mass is known, the density can be calculated.
im not understanding your question i think. when we normally ask how much something weighs, we are talking about the mass of the object multiplied by the earth's gravitational field near the earth's crust, the object doesnt necessarily have to be on the earth's crust though; its just a reference point. if more than one substantial gravitational force is applied to an object, the addition of the two, or more, vectors would give you the resulting gravitational force on that object
Hayder Al-Amiri. You can multiply volume by density to get the mass of any object. While we the volume of the earth is easily calculated the density. The way they figured out the density was to solve for mass, not the other way around. The equation he gave allowed for the mass of objects to be determined based upon the acceleration the object exerts on other objects. It's kind of a domino affect. You solve one variable, which allows to solve another variable, and another and so on.
The earth does have a weight. If it were floating in empty space it would have no weight, but intact it is orbiting the sun. The sun has a gravitational pull on the earth, so it has weight.
An object only weighs something if it is has acceleration. The equation is force=mass x acceleration. In the case the earth is rotating at a fairly constant velocity which does result in an acceptation. Acceleration is velocity^2/radius of the orbit. Given that the mass of the earth is 6x10^24 kg, the average velocity of the earth is 30 km/sec, and the distance from the earth and the sun(the radius of the orbit) is 149.59787 million km, then the force is calculated to be 3.6 x10^24 N .
having more mass above you in that situation does not affect the gravitational field effects on your body. the gravitational field is inversely proportional to the distance between two objects; as r decreases, g increases. g=G(m1m2)/r. so as you approach the earth's core, you experience a stronger pull to the center from gravity than you would on the surface
Sir Issac Newton is a "small time" physicist lol. The source if gravity is not mass, it's energy and momentum, which mass has. This explains why a mass-less beam of light can't escape a black hole.
But, weight is gravity and mass. Guy standing on the ground may weigh 200lbs with 200lbs mass and 1g. The same guy floating in space would weigh 0 lbs with 200 lbs mass and 0g. The earth is floating in space so its weight is 0 but its mass 60E24 Kg.
The earth does have weight. Weight is essentially the force an object exerts due to gravity. All objects attract each other and cause a gravitational attraction . Most objects are so small the gravitational attraction is negligible. In the case of the earth; the reason it's orbiting is because of the gravitational attraction of the sun.
I think there is some confusion about weight. Objects that orbit other objects do in fact have weight. This is because of the gravitational pull of the earth due to the sun. There are also impacts due to the moon, asteroids, and planetary bodies, but they are significantly weaker. If an object were floating in space and not moving it would have no weight. But because it is orbiting due to a pull of the sun, the earth does in fact have weight.
@dustin i would rather explain it like mass is an intrinsic property of matter and does not change. 1kg on earth is 1kg on the moon is 1kg floating in outer space. weight is a vector quantity that has a magnitude = mass x gravity. 9.80N/kg is the gravitational field strength for objects near earth's surface. replace that constant with whatever gravitational field is acting on you and you get your weight with respect to it. i would argue that you still have weight while floating in space.
the jokes on you, the centre of the earth is liquid and the camera that they used on the moon probably wouldnt have picked up lights from any stars aside from the sun
Its mass is consistent. When talking about the weight of the Earth, you need to have something to reference it with. Most of the time, we Earthlings compare weights where g=9.80m/s^2.
Another way to figure out the force is to use the equation he gave you and use the mass of the sun, the mass of the earth, and the distance between them and you get about the same answer I calculated. This doesn't take into account an elliptical orbit or the pull of other objects such as the moon.
No, the center is solid. There is an inner core (which is solid) and an outer core which is liquid. The center is not the same as the core because the center not even three dimensional its only a point. But the metal at the center is solid.
Maybe I misunderstood your question. If I understand what you are trying to say, then the answer is that the mass of the space debris is so negligible compared with the mass of the Earth that g is not substantially affected. Given Earth's mass at around 6x10^24 kg, you can see that to get a .01% change in g, you would still need a very large mass.
You barely mentioned the most interesting part of this question, namely what the weight of the earth is. As it is in free fall orbit, my guess is that it´s weightless.
No. Because there is no material that will bear the hit. Additionally, pressure will kill you. The deepest hole dug is only 7.8 mile Dept and it took 20 years. Cheer! Keep Looking for answers...
A way to think of weight if the earth to Imagine a hammer thrower spinning in a circle and spinning the earth. An old fashioned bathroom scale is a spring that is used to calculate weight. If you used a spring instead of rope for the hammer thrower, you would see the spring stretch, which means force ( or weight) could be measured.
the weight of the ocean would be sucked into the planet kinda like a leak from a balloon but backwards and also it pretty easy to tell if the planet is hollow or not just by its gravity.
Aren't the instruments that are used to measure the planet made with the assumption that the planets attraction is that strong for them to get a proper reading..?
As I calculated in an earlier post the weight of the earth about 3.6 x10^24 N or 8.1 x10^23 pounds. Of course, the weight of an object does change as it gets closer to an object, so because the earth's orbit is elliptical and not circular, the weight will fluctuate.
0:31 Good. I'd hate to see a giant man surcome to those tidal forces; -watching his mass crush himself into a ball, before turning into a molten amalgam with the Earth he's holding. :P Cool video, thx!
Whats the critical mass for a sphere? In space meteors etc are not spherical, but all planets, stars, black holes etc are... So considering they are all bigger than meteors there has to be a critical mass to gain a spherical shape, right?
Wow, two bowling ball placed near eachother will attract eachother. I didn't know it could be this easely replicated of Earth... But I understand that that gravitational force of a bowling ball is very very very small.
When you take a picture from millions of miles away, it will have low quality. Even just a few miles is difficult, dozens of satellites fly around taking tons of pictures and connect them to get the high quality you are used to. Also, they are in black and white because they measure only one wavelength, helping the picture be easily transmittable across large distances and reconstruct-able through Cosmic Background Radiation (static).
same reason on land herbavours dont have to hunt for there food meaning expending less calories to get a steady diet where as predators have to expend more calories but when they get something they get allot more energy from it
thats what i'm saying, how would you know the gravitational field is 9.8? as you progress towards the core, it would change. How would you calculate the weight from a changing value on different sides of the earth.
So you didn’t answer the question. The mass of an object is not its weight. Assuming you could stop earth and put it on a scale with the suns gravity pulling on it how much would it WEIGH?
it would not as that the earth does not have 1 point where all gravity comes from but all the points of those atmos combined do so if you have more points of gravity above you you would feel a lower pull as it evens itself out
were talking about surface here ... as you progress to the core more mass would be on top of you making the force a bit more even but with the fact that we dont really visit the core yet we referr to the surface . also climbing on the mount everest wouldnt make you feel lighter . as the earth if it would be sized down to a billiard ball. it with its mountains would be smoother than an actual billiard ball
But how about all the diferent types of materials on earth? We have a lot of water, but all the dirt and rocks and what else all have different densidies. Does this way of calculating it's weight also take this in consideration? Or doesn't it even matter?
Earth weigh's approximately 13,170,000,000,000,000,000,000,000 pounds.
That's 13 septillion, one hundred seventy - sextillion.
Have a nice day.

Yes
The Earth's mass is, but it's constantly weightless, well not quite, attracted to the Sun's mass, and that is attracted to some black hole in the middle of our Milky Way Galaxy, and that is intertwined between numerous other black holes.
So how much is that in pounds

The Earth is weightless. Mass and weight are not the same concept.
What is the mass specifically?
The earth weighs 9999,99999,9999999,999999,999999 mega tons HAVE A GREAT DAY

Great video. I had always wondered how the Earth's mass was calculated.
when he was tossing the earth in the air i was falling on the ground

Can you measure the mass of a person by applying the same formula to the equation?
Ur mom
Plot Twist, turns out he was Atlas all along, and the earth he is holding is NOT a model.

the outer core is liquid but the pressure on the inner core causes it to be solid
That's not right, you forgot the Moon's gravity acting oppositely to Earth`s

Don’t know why the distance of the earth would matter when it never changes
May be less because we are drilling & burning so much fuel to atmosphere every second the mass would be far less
Isn't it kinda hard to tell how much the Earth weighs since it's floating in space & we're standing on it.
So, this is what someone who never went to school looks like... where did you learn to type?
I learned more here then in my physics class
Great video, i remembered my physics class
did you go bowlin after this video?
the centre of the earth is not liquid, the pressure is so high that the core is solid ;)

Weight unit is N
Mass unit in kg
You have to tell us weight not mass
i've been bowlen
the jokes on you, the centre of the earth is liquid and the camera that they used on the moon probably wouldnt have picked up lights from any stars aside from the sun
The title should be: What is the mass of planet Earth.
You can measure it based on seismic waves. You could look at the fact that you are alive, so earth has a magnetic field, so it has a core.
El problema es que la gravedad no ha sido probada aun hoy en dia. Saludos

Can you explain how scientists are able to find the cross sections of earth, stars and other planets??
You barely mentioned the most interesting part of this question, namely what the weight of the earth is. As it is in free fall orbit, my guess is that it´s weightless.
there is no distance between two objects where there is not a gravitational interaction between them.
Earth weighs about 13,170,000,000,000,000,000,000,000 pounds
Hey Ben! Have you ben bowlin lately? :D just had to, great video btw:)
like si veniste de robot de platon :v
How would you get the weight of the earth? Since for objects on Earth's surface you multiply mass by the gravitational field..
Can you build a tunnel through the earth to go from the US to China?
no, in the center, the pressure will kill you
I can build everything on ur order but if u befriend me
No. Because there is no material that will bear the hit. Additionally, pressure will kill you. The deepest hole dug is only 7.8 mile Dept and it took 20 years. Cheer! Keep Looking for answers...

its hard but think about it kilo's didn't exist in the universe its just a measurement we've created

maybe the weight of the earth is something they don't want you to know
That's a unit followed by 21 zeros..... Six Sextillion Tons
Aren't the instruments that are used to measure the planet made with the assumption that the planets attraction is that strong for them to get a proper reading..?
so long story short its 13 septillion pounds
No tons 1 ton 2000lb
As I calculated in an earlier post the weight of the earth about 3.6 x10^24 N or 8.1 x10^23 pounds. Of course, the weight of an object does change as it gets closer to an object, so because the earth's orbit is elliptical and not circular, the weight will fluctuate.

weight depends on gravity , so since you're weighting a planet there's no reference gravity exept the planet itself so it has no weight :)
He already told you, 6x10^24 meaning 6 followed by 24 zeroes. 6,000,000,000,000,000,000,000,000 tons.
Earth’s real weight is approximately 6000000000000000000000000000 pounds

Yes, that’s call hydrostatic equilibrium. If I remember correctly, it’s a few 100 Km in diameter.

thats what i'm saying, how would you know the gravitational field is 9.8? as you progress towards the core, it would change. How would you calculate the weight from a changing value on different sides of the earth.
I already know all this but still nice vid.
Haha - oh, man. It never makes it into the final edit, but - for the record - I do try. Thanks for watching!
If u think about it the earth weight is infant because people are always being born and so are animals
I have a question, why are some fish predators and others non predators?
If I'm right, the weight of Earth in tonnes are 5,980,000,000,000,000,000,000 tonnes.
correct
I feel like you didn't make the proper distinction between mass and weight. You told me the mass but not the weight.
No gravity! What do you call the Sun?
Its liquid metal, or else there would be no magnetic field, think about it.
Would you mind repeating that please--13,170,000,000,000,000,000,000 times
What if the objects are actual magnets? Or a magnet and an iron ball?
So the entire equation is based on a negligible force...
So you didn’t answer the question. The mass of an object is not its weight. Assuming you could stop earth and put it on a scale with the suns gravity pulling on it how much would it WEIGH?
I want to know the exact calculation about how many time heavier is Jupiter compared to Earth????
loved it, at least you said mass.
The answer to the question is6-sextillion ton with a unit followed by 21 zeros that's your answer
it would not as that the earth does not have 1 point where all gravity comes from but all the points of those atmos combined do so if you have more points of gravity above you you would feel a lower pull as it evens itself out
1:55 DARY! LEGENDARY!!!

What wight of the earth? Its mass= 6*10 into 24 kg. How do you calculate the wight=mg?
Basically 6,000,000,000,000,000,000,000,000 or six septillion kg
after this video i am now a Fat-Earther
g=m1m2/r2 so the m1 which is the mass of earth so its gravity should change right!
But how about all the diferent types of materials on earth? We have a lot of water, but all the dirt and rocks and what else all have different densidies. Does this way of calculating it's weight also take this in consideration? Or doesn't it even matter?
thats light for chuck norris
