Energy and Work in Circular Motion

This post is part of the HSC Physics Syllabus Module 5: Advanced Mechanics.

In this post, we will investigate the relationship between the total energy and work done on an object executing uniform circular motion. To do this, we also need to know a little bit about torque.

 

Torque

Torque follows the formula:

\tau = r F
  • F is force
  • tau is torque
  • r is the radius from the fulcrum
