They Drop A Feather And Bowling Ball In The World's Largest Vacuum Chamber To Demonstrate Gravity
You've probably heard of air resistance in science class. This is the only thing on earth that will cause objects to fall at different speeds. We can watch feathers and a ball fall, and wonder which one will hit the ground first. This fascinating presence of gravity is better explained by Newton's Law of Gravity. In the absence of air resistance, both the feathers and the ball are in a state where they are free falling. In a free fall state, these two objects have only once force, gravity. Will the ball hit the ground first or will the feathers get there ahead of the ball? Watch what happens when both the ball and the feathers drop at once in the presence of gravity.
