In this lesson we extend our knowledge of Uniformly Accelerated Motion to include freely falling objects. We talk about what FreeFall means, how to work with it and how to identify and object in FreeFall.

In this lesson we continue to use what we have learned about solving Uniformly Accelerated Motion (UAM) problems. This problem is more complicated because it involves two, interconnected parts.

This is an introductory lesson about Uniformly Accelerated Motion or UAM. I show examples of 5 different objects experiencing UAM, some are even in slow motion. We also learn my simple way of remembering how to use the UAM equations.
