@@metroid1 Of course.

@@g4macdad Wait so only atheists believe in gravity?? I really don't understand what atheism has to do with this video. But if ur wondering why scientist make a smile when theories gets proven correct, its simply the fact that in science u have to prove to be right. Even tho we know pretty much 99% that a theory is correct we still have to test and prove till we truly know the facts. On the other side we have people like u, who i assume is religious. Would u say believing a book written by who ever 1000+ years ago is being critical? Sure u can believe it, that's up to u and i have no problem with that. But in science we actually try our best to look for the facts and explore this wonderful world and universe. If everyone was just gonna read one book and not keep looking for new answers we would not be here on a computer watching this video right now. U should never underestimate the importance of science. And also, there are multiple scientists with religious beliefs.

Wasn't Newton the one who predicted that a feather and a brick would fall down at at the same speed if air resistance wasn't present?

@@KissMyFatAxe This test didn't answer the question if things are upside down how that things are attracted towards the planet

IF, you were inside this vacuum chamber and you wanted to first toss the bowling ball and feather up to the height where they fell from, then obviously the Force required for the upward proper acceleration on the bowling ball would need to be much greater than the force required for the proper acceleration on the feather. After they reach the same height they fall at the same rate regardless of their masses. That is because there is no force downward when an object is in the coordinate acceleration of free fall. The same experiment can be done in an accelerating spaceship.

that would be like an actual video now wouldn't it, asking for too much

its 2016, you can make the video run at normal speed yourself.

It's 2017 ;)

Mikes8899 Earth is flat , BBC lies!

you never know, maybe it was sped up!

I am a free thinker like einstein. he would propose that if you can change the speed of the video feed then it is impossible to deduce what initial speed the ball was falling. perhaps without an atmosphere the pressure would cause gravity to have less of an impact, we do see the ball struck the card board at significant force though that is is probobaly not the case, but without a reference its impossible to say for sure. some other interesting observations. 2:53 shows 1 ball 1 feather starting to drop, then next clip is ball and like 7 feathers? ok odd..... then at 4:16 the feather shows much more wind resistance and the ball dropping faster than the feather. and then back to the 7 feathers and 1 ball clip. so badly edited

> This video would be much better for students if they first showed the real-time video Yes, maybe... However, the entire fall takes less then 3 seconds, so that it would be difficult to observe that the two bodies are perfectly synchronized all the time...

@@magoninhogamer > just put a small piece [...] And what will this prove?

@@alexleibovici4834 The much lighter paper (feather) without buoyancy/drag coeficient of medium fall at the same rate as the much heavier notebook/book/object.

So, this means that is not about the weight!!!!

@@lucadipietro2310 Of course its a theory, but that test didn't prove his thought that air resistance was the cause of objects falling at a different rate. The definitive test he made was to create 2 iron balls of different weights but of the same diameter.

닥쳐 한국어 여기 초밥이 없어

Was it provided that both the bowling ball and feathers had the same weight ?

No, since their huge different mass is the essence of the experiment. The bowling ball is much more massive then the feathers, instead in vacuum they "fall" exactly the same.

Power of vacuum? Strange view. It is just "nothing". So we just see gravity working in the vacuum experiment. It is the air that has "power" in the non-vacuum experiment.

@Sebastian -> It all depends on the reference frame that you are. In a way the air has the power of adding friction with its particles, while on the other hand the vacuum "has" the power to remove all friction by the absence of any particle. The expression "power" was used in its philosophical sense, not in its physical meaning. It was just an expression of WOW, how amazing vacuum can change the behavior of objects...

can u explain me why feather moved it "hair" at the beggining of falling down? i wonder

@@merihim666 I notice this detail and I don't have an exact answer, but I suppose that this is due not being a perfect vacuum. Editing: found another 2 comments here: 1) "Inertia." 2) "For every action there is an equal but opposite reaction. As the feathers accelerate from zero the parts that you see move are actually still standing still until they are acted upon. While it looks like they are moving up they are actually being pulled down. Once all parts of the feather reach the same speed there will be no movement." My conclusion: the feather is not a rigid body, and the feather undergoes sudden acceleration. The softer parts are flexible, and react to this.

@@merihim666 it’s not a perfect vacuum, there is still a small fraction of air in the chamber causing small amounts of feathers to flutter

You r a gee also i think the air was paid to dip

it really does look like its being lowered down using some sort of string up until it comes in contact with the ground though lmao

Air resistance doesn’t play a factor, does it? Clearly this vid shows that it does. But I was thinking about flying from the equator over the North Pole and back to the equator on the other side of the earth. The plane took off we a relative speed of the earths movement at 1000 mph, some how slows down to nearly nothing at the North Pole then manages to regain that lost speed? Also on take off the plane is getting the rotational force of the air on one side of the plane, then once past the pole it’s on the other side of the plane. Do we just not fly over the North Pole due to this? I see pilots keep it simple and assume a “flat and stationary earth”. How the heck can they do that if the atmosphere is moving one way then the next once over the pole? Just trying to learn here. Thanks

Yes how u gessed me i would partner to galileo !

+Jay Bluff What are you talking about, even if that was true why would they show the balls falling at a different rate after they have shown them fall at the same rate just before... Use your head.

I agree. He totally misrepresented Einstein

What if the objects WERE standing still? Many possibilities in media circles and maybe he doesn't lie.

any links for more info on this?

I came to the comments to find an explanation about the last part because i found it confusing too.

Agreed. Einstein was merely saying which objects were falling, and which were not with no frame of reference would be impossible to tell. They would only be moving relative to each other. Or more specifically the man in space being picked up by an elevator that accelerated at 9.8 m/s^2. Would cause the man to not know if he entered a gravitational field or if he was being accelerated by the make believe elevator. As to why everyone is obsessed with dropping paper or whatever and that this was some how faked is disappointing to see. It doesn't matter what you drop. They took all of the air out. Drop a dude with a parachute it won't work. I sure hope NASA didn't spend millions on this vacuum chamber to simply fake experiments.

To make sense of this comment - imagine two bowling balls in space 1 metre apart at rest with respect to each other and not rotating around each other. Because they both have mass, there is a small but present and measurable quantity of gravitational field between them. Two equal mass bowling balls 1 metre apart will come together at the mid-point of 0.5 metres. Now consider the feather and the bowling ball coming together under gravity. The feather weighs barely anything compared to the bowling ball. The feather will experience the same initial acceleration towards the bowling ball, but the bowling ball will barely accelerate or move towards the feather at all. The feather is travelling almost the whole (0.9999 metres) distance and its acceleration towards the bowling ball is less at future points in time due to not being as close to the bowling ball. Now consider a bowling ball and an atlas stone (that strong men lift on TV). Because the atlas stone weighs about as much as 20 bowling balls give or take, when they come together, the atlas stone has migrated only 5 cm towards the bowling ball, whereas the bowling ball has moved 95 cm from its initial position (in the frame of reference that defines both as stationary). When comparing the feather and the atlas stone, the feather travels practically the entire metre and the atlas stone moves only a few microns. You would say that the bowling ball falls towards planet atlas in 95% of the time the feather does - when dropped individually. Now the earth is just a giant atlas stone that has a mass of 6 x 10^24 kg. For ease of calculation we'll say it has the mass of 10^24 bowling balls. When you drop a bowling ball 10 metres, the earth moves up at (10/10^24) = 10^-23 metres (1/87 million of the width of a proton). If the bowling ball is moving at 14 m/s it will hit the ground around 7 x 10^-25 seconds before the feather (the time it takes light to travel 1/4 the width of a proton). For this to be correct, the bowling ball and feather must be dropped one at a time, or else the earth is moved up for both the bowling ball and feather by their combined mass.

Yes, but not if they fall together :)

not really, since they are right next to eachother

Me bro

Me broo

us

Even with 3 (or more) points of reference you still can't tell what's moving and what isn't. For instance if object A (an apple) and object B (a bird) were both seemingly hurling towards object C (the earth) and even though object A seems to be falling faster than object B, who is to say that the bird isn't sitting perfectly still in space while the apple is moving away and the Earth is moving toward it? Yeah I know- you're mind just got blown again ;)

@@Rick-the-Swift sure you can tell. Compare the distance between the objects and you will know which is moving. In your example, we know earth will be static so compare a to c and b to c to see which one is moving.

@@HalcyonVoid But we already know the earth is not static and is moving as well. It's what we think we know which causes conundrums, no? Have you ever heard that every single point in space is potentially the very center of the expanding universe? And that if we were to view the universe from any given galaxy- it would seem as if almost every other galaxy were moving away from our perspective? Isn't this an important aspect of Einstein's 'relativity'? If we knew where the so-called 'big bang' happened, we'd know the true center of the universe, and what is truly static, but as it stands you or I could be at the very center and everything else swirling around us. Not likely I know but it's possible I believe, haha Cheers.

@@Rick-the-Swift by that logic, then we could never tell if a car is moving. Obviously we can because we are basing it on a reletive view of the objects

IF, you were inside this vacuum chamber and you wanted to first toss the bowling ball and feather up to the height where they fell from, then obviously the Force required for the upward proper acceleration on the bowling ball would need to be much greater than the force required for the proper acceleration on the feather.
