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:
