Feather and Coin

A feather and a coin are allowed to simultaneously begin falling from rest while inside a glass tube. In the first experiment, the tube is open to the atmosphere and the feather flutters down much more slowly than the coin. In the second experiment, the tube is evacuated of air and the feather and coin fall together.
Equipment:
- Glass tube-feather-coin system
- Vacuum pump and hose
