Prof McCarthy 17:04, 5 January 2012 (UTC) Go for it. It it does this it must have a component of its acceleration along the direction of its velocity. In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. Tangential velocity If motion is uniform and object takes time t to execute motion, then it has tangential velocity of magnitude v given by v = s t f = 1 T Period of motion T = time to complete one revolution (units: s) Frequency f = number of revolutions per second (units: s-1 or Hz) 4 I would be pleased to take on the task of merging these three articles. Uniform circular motion occurs when an object travels along a circular path at a constant speed or angular velocity. In such a motion the speed may be same throughout the motion but its velocity (which is tangential) is different at each and every point of its motion. This text blends traditional introductory physics topics with an emphasis on human applications and an expanded coverage of modern physics topics, such as the existence of atoms and the conversion of mass into energy.

[itex]r[/itex] is the radius and [itex]\alpha[/itex] is the angular acceleration. A particle in uniform circular motion is identified by two characteristics: It is moving at a constant speed v and is moving in a circular path with a radius r. Then the acceleration of the particle is directed radially toward the center of the circular path and has magnitude v2/r. This motion refers to the circular motion if the magnitude of the velocity of the particle in circular motion remains constant. Non-uniform circular motion Motion in a circle with non- constant speed Centripetal acceleration Towards the center changes direction Tangential acceleration tangential to circle, changes speed = 2 is speed at that instant, does not have to be constant = Since the radius is fixed, it follows In the case of uniform circular motion, the angular speed & acceleration remains constant, whereas the velocity differs.
