Unit 3 · Work, Energy, and Power
Chapter 3.1
Kinetic Energy and Work
A sideways push can shove as hard as it likes and never change an object's speed. Only the part of a force along the motion trades energy.

By the end
- 01Compute kinetic energy and explain why observers in different frames measure different values
- 02Compute work by a constant force from its parallel component, and as the area under a force–displacement graph
- 03Apply the work–energy theorem
- 04Classify forces as conservative or nonconservative, and account for the energy friction turns into thermal energy and sound
