Anyone else notice that he moved his hands down as he fell? And that the stone maintained the same rate of fall as him? That’s not weightless.

All objects fall at the same rate, ask Isaac Newton.

All things regardless of weight fall at the same rate in a vacuum

What a moron he tossed it in the air as he jumped looks like gravity still works its not floating

Mid air or not it’s not weightless once it lands

Like they say, it's not the fall that kills you, it's the sudden stop 😁

he moved his hands down, or else it would have still been in his hands and not floating

I was "weighting" for him to land, catch the rock and tear the muscles in his lower back or biceps then dropping the rock on his foot...

well neither is weightless. if you was weightless. you wouldn't of hit the floor. and that folks is exactly why college dumbs our kids down.

Yeah, it’s how NASA does all their weightlessness shots.

an object that is weightless will not fall at all, but where there's gravity only certain gases are weightless. When you jump up you will, for a brief moment experience the sensation of weightlessness at the apex of your jump, but that's just a sensation. Neither he nor the stone were actually weightless.

Dude threw the rock slightly above his hands to give the illusion it’s weightless. I seriously hope this is ai and this man isn’t teaching anything to anyone.

He didn’t demonstrate weightlessness, he demonstrated gravity.

If it was weightless gravity would have no effect on it.

I'm sure Democrats would pay 10's of millions to further that study. Especially when 10% comes back in campaign donations.

does gravity have any to do with it. more mass, more gravity influence

Sounds like he's trying to say because they fall at the same rate that the weight does not matter!😲🤔

Lewin uses this to explain that astronauts in orbit feel weightless because they are constantly "falling" around the Earth at the same speed as their spacecraft, not because gravity has vanished. This is a classic demonstration of Newtonian mechanics and gravity, often highlighted to show that when accelerating with gravity, objects in hand behave as if they are floating.

he pulled his hands down twice after he jumped, slow motion tells all.

NO such thing as weightless, even in space something has more mass than you and therefore you are in its gravitational field and have weight.

The only thing that changes the speed something drops is wind resistance. Since himself and the stone have none they fall at the same speed.
