Work and the Work-Energy Theorem
Helpful before this lesson
- Not completed: Force and Net Force
- Not completed: Newton's Second Law of Motion
- Not completed: Friction
These topics can make this lesson easier, but you can start now.
Learning Objectives
- Students will understand work as transfer of energy
- Students will calculate work done by forces
- Students will apply the work-energy theorem
Core Concepts
- Work: force applied through a distance
- W = Fd cosθ (depends on angle between force and displacement)
- Work-energy theorem: net work equals change in kinetic energy
