Radial acceleration in circular motion ( related to period)


Uniform circular motion, that is constant speed along a circular path, is an example of a body experiencing acceleration resulting in velocity of a constant magnitude but change of direction. In this case, because the direction of the object’s motion is constantly changing, being tangential to the circle, the object’s linear velocity vector also changes, but its speed does not. This acceleration is a radial acceleration since it is always directed toward the centre of the circle and can be computed by the period of the circular motion and the vector directed from the centre of the circle and equal in magnitude to the radius.
