# Ch 4: Energy, Power & Momentum in Physics

The video lessons in this chapter on energy, power and momentum help middle school students explore these physics concepts in a fun and engaging manner. Students can take self-assessment quizzes to test their knowledge of topics like kinetic energy, linear momentum and the work-energy theorem.

## Energy, Power & Momentum in Physics - Chapter Summary

Use the video lessons found in this chapter to reinforce the physics concepts of energy, power and momentum your students have already learned. By watching the short videos, students can get a better grasp of the nature of energy, the relationship between work and energy and how to calculate the amount of work done on an object. Students can also discover how mechanical energy obeys the law of conservation energy and explore how an object's moment is impacted by mass and velocity. The video lessons offer a relaxed environment for learning and provide timelines to help students jump from one topic to another. Instructors are also available to answer any questions regarding this chapter.
