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?

Lesson Notes
The Lesson Notes are intended to be printed and used when watching the video. They are structured to allow students to follow the video, record some notes, and leave the video with a document that can be referred to as their learning continues. The Lesson Notes are available as a PDF. Permission is granted to print the notes or to include a link to them from a learning management system.

Additional and Related Learning Tools
Learning takes effort. Watching a video is a relatively passive activity. It's one thing to listen to a video presented by a person who understands the material. But it's quite another thing to apply the information from the video in an effort to personally understanding the material. This page lists a variety of tools that can used to put the new learning to use. The tools include those that can be used by students and those that can be used by teachers with their students within the classroom. Related resources are also included among these tools.
