Question

A tube of air contains a feather and a coin. both objects are dropped at the same time. the coin falls faster than the feather. However when air is removed from the tube to create a vacuum, both the feather and the coin reach at the same time. Explain why this happenes?

Answer 1

Because gravity treats all mass equally. It doesn't treat heavier objects with greater force. All objects experience the gravitational pull equally. Making the two different weights reach the ground together simultaneously despite their weight differences.
