Falling bodies

Science presenter Jon Chase describes Aristotle’s and Galileo’s theories about falling bodies. With the help of some students, Jon demonstrates that two balls of similar size, but different mass, dropped from a window will land at the same time. However, a hammer and a feather dropped at the same time will not hit the ground at the same time. This is due to air resistance.

Footage from the Apollo 15 mission is shown, in which astronaut David Scott demonstrates that in the absence of air resistance, both the feather and the hammer accelerate at the same rate.
