High Quality Content by WIKIPEDIA articles! "The radian per second (symbol: rad·s 1 or rad/s) is the SI unit of angular velocity. It is also the unit of angular frequency. The radian per second is defined as the change in the orientation of an object, in radians, every second. 1 radian per second = 1 2 hertz (Hz) 0.159155 Hz 57.29578 degrees per second 9.5493 revolutions per minute In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed of an object and the axis about which the object is rotating. The SI unit of angular velocity is radians per second, although it may be measured in other units such as degrees per second, revolutions per second, degrees per hour, etc. When measured in cycles or rotations per unit time (e.g. revolutions per minute), it is often called the rotational velocity and its magnitude the rotational speed. Angular velocity is usually represented by the symbol omega ( or ). The direction of the angular velocity vector is perpendicular to the plane of rotation, in a direction which is usually specified by the right hand grip rule."
