angular velocity to linear velocity

The formula to calculate the linear speed  expressed in meters per second [] from the angular velocity  expressed in radians per second [] is:



where:

•  is the linear velocity expressed in meters per second ()
•  is the angular velocity expressed in radians per second ()
•  is the radius expressed in meters ()

For example, let's consider a vehicle with wheels having a radius of 10 centimetres. If the rotational velocity of the wheels is 20 rad/s, the linear speed of the vehicle is given by:
