Work, Energy, Power Lectures

Work Lecture

This video lecture introduces the concept and math of work in both the horizontal and vertical directions.

Energy Lecture 1

An introduction to energy and types of energy with an emphasis on kinetic energy and gravitational potential energy and conservation of energy.

Energy Lecture 2 - Pendulum and Roller Coasters

This lecture focuses on conservation of energy related to pendulum motion and roller coaster rides.

Energy Lecture 3 - Spring Potential Energy

This lecture introduces elastic or spring potential energy and how it applies to conservation of energy.

Non-Conservative Work Lecture

This lecture covers non-coservative work and how energy is lost due to non-conservative forces such as friction or air resistance.

Power Lecture

This lecture discusses mechanical power (which is different from electric power).
