1. Angular and Linear Velocity:
Lesson 38

2. LESSON OBJECTIVE:
Analyze situations involving pulleys or sprockets to study angular velocity and linear velocity.
How are angular and linear velocity related in circular motions?

3. DEFINITIONS
Angular velocity: angle of rotation about the center of a circle in a unit of time 𝜔= 𝜃 𝓉 where 𝜃 is expressed in radians and 𝓉 is time.
Linear velocity: distance traveled by each point on the circle in a unit of time.

4. FACTS:
Larger pulleys rotate slower than the smaller pulleys.
In connection with the pedal and rear sprockets of a bicycle, the pedal sprocket is called the driver and the rear sprocket is called the follower.

5. Please get out the worksheet “Angular and Linear Velocity – Lesson 38” so I can show you an example of how to use angular velocity.
