Rotational Kinetics Terms and Formulae Terms Rotational motion - The motion of any object in which every part of the object rotates about a common axis in a circular path. Angular displacement - The angle swept out by the circular motion of a particle. See definition of angular displacement Radians - A unit of measuring an angle. The relation between radians and degrees is as follows: 1 revolution = 2 Π radians = 360 o Average angular velocity - The average rate at which an object rotates in a circular path. See formula. Instantaneous angular velocity - The instantaneous rate at which an object rotates in a circular path. See formula. Angular acceleration - The rate of change of angular velocity. See formula. Right hand rule - The rule by which the direction of a rotational vector can be found: take your right hand, curl your fingers and stick your thumb straight up. If you let the curl of your fingers
