WebThe angular speed is the angle that an object moves through in a certain amount of time. The angular speed has units of radians per second (rad/s). There are 2π radians in a full circle. At a distance r from the center of the rotation, a point on the object has a linear speed equal to the angular speed multiplied by the distance r. WebSince the s.i unit of angular velocity is rad/sec, and we say speed =angular speed×radius. Why do we still keep the s.i unit of that speed as m/s instead of (rad/s × m)
