Dropping a Feather and a Coin in a Long Vacuum Chamber—Gravity Demonstration

Описание: In this video I show you what happens when you drop a feather and a coin in a vacuum chamber. Then I show you a what happens if you drop a golf ball and the moon on the earth at the same time from the same distance. I talk about inertia and how things always fall at the same acceleration no matter what their mass is.
