What do the deniers say about the experiment where the astronaut dropped a feather & a hammer which both fell at the same speed?
Also the film of the moon rovers driving showed the moon dust falling back to the surface without being thrown up in clouds like it would on earth?
Still, ya can’t beat a good conspiracy!Newton’s experiment works just the same on Earth.So why did the Grand Slam bomb reach a terminal velocity of around the speed of sound unlike lighter bombs ?.The fact is if you push a tank out of a plane it will be travelling at a much faster speed than a car when it hits the ground.Just as the terminal velocity of a hammer is greater than that of a 1p coin whether here or on the Moon.
Why would you expect fine dust to fall back to the ground ‘more’ effectively in a ‘lower’ gravity environment than on Earth ?.Oh wait ( sand ? ) in Earth’s gravity would explain it.
From memory, it was Galileo who stated that an object’s mass doesn’t affect it’s rate of descent. That’s about 100 years before Newton. The biggest problem here on earth is air resistance. Two different masses with exactly the same shape will fall at the same rate. On the moon, that experiment demonstrated that with no factors other than gravity, objects fall at the same rate, proving that mass is irrelevant.
As far as terminal velocity is concerned, that is simply the equilibrium of forces acting on the falling body. In effect, the acceleration due to gravity is cancelled out by the resistance of the air on the falling body. Clever aerodynamics can increase or decrease that value.
