The formula to calculate the linear speed  expressed in meters per 2nd <> indigenous the angular velocity  expressed in radians per second <> is:



where:



 is the direct velocity to express in meter per second () is the angular velocity to express in radians per second () is the radius express in meter ()

*

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