Centripetal(Centrifugal) Acceleration


Acceleration, in physics, is the rate of change of velocity of an object. An object’s acceleration is the net result of any and all forces acting on the object. 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 calculated by the object’s linear speed along the circular path and the radius of the circle.
