Angular and Linear Velocity: Lesson 38

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?

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.

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.

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