Free Falling

This source is helpful because it talks about a misconception of free falling; that heavier objects fall faster than the lighter ones. This clip gives examples of why this is not true, by telling us that Galileo discovered that all objects fall at the same speed towards the earth, and the "lighter bodies fall at a slower rate due to the resistance of the air." This video also shows this through showing an experiment conducted by Robert Boyd, where he took out the air of a bottle, with a feather and a penny inside. When flipped over, the feather and the penny fell at the same time, thus proving that air resistance is the reason things fall faster than others.
