Forces, Energy, and System Analysis Video Tutorial

The Forces, Energy, and System Analysis Video Tutorial explains the importance of a system analysis in keeping track of energy for any given motion scenario. The distinction between conservative and non-conservative forces and the relationship of each to the total amount of mechanical energy is discussed.  Numerous examples, illustrations, and analogies assist in the explanations. The video lesson answers the following questions:
  1. What is meant by a system and how can it be used to conduct an energy analysis?
  2. What is a conservative force and how is it related to the amount of mechanical energy?
  3. What effect do non-conservative forces have on the energy of a system?
