Angular Speed
- Any object travelling in a uniform circular motion at the same speed travels with a constantly changing velocity
- This is because it is constantly changing direction, and is therefore accelerating
- The angular speed (⍵) of a body in circular motion is defined as:
The rate of change in angular displacement with respect to time
- Angular speed is a scalar quantity, and is measured in rad s-1
Angular Speed
When an object is in uniform circular motion, velocity constantly changes direction, but the speed stays the same
