Angular velocity is defined as the rate of change of angular displacement with respect to time. It is usually expressed by a Greek letter (omega). Mathematically, angular velocity is \\\\(\\omega =d\ heta/dt\\\\)If a body is rotating at the rate of N r.p.m. (revolutions per minute), then its angular velocity,\\\\(\\omega=\\dfrac{2 \\pi N}{60} \\\\)rad/s
