Lecture 11: Potential Energy
Objectives: In this lecture, students will learn to- distinguish between conservative and non-conservative forces
- relate force to potential energy
- construct an expression for the potential energy associated with a force
- define the total mechanical energy
- relate the chance in total mechanical energy to the work done by forces not included in potential energies
- apply energy conservation to example problems
