PHY221
Rotational Statics and Dynamics

_______________
 

Overview

Purpose
We have looked at motion and forces in some detail now. What we have left out, however, is rotation. It turns out that all of the concepts we have looked at so far have their "counterparts" in rotation. This means we have rotational acceleration, velocity, displacement, and so forth.

Prerequisites
o Successful completion of work, energy, and momentum competancy

_______________
