VIDEO: Misconceptions About Falling Objects

Physics is an interesting field of science because it is the study of real life every day objects and forces. We perceive and experience them constantly, but to fully understand them is sometimes more complicated. Sometimes misconceptions grow when we start to learn part but not all of the big picture.

If you drop a heavy object and a light object simultaneously, which one will reach the ground first? A lot of people will say the heavy object, but what about those who know both will land at the same time? What do they think? Some believe both objects have the same gravitational pull on them and/or both fall to the ground with the same constant speed. Neither of these things is true, however. The force is greater on the heavy object and both objects accelerate at the same rate as they approach the earth, i.e. they both speed up but at the same rate.
