SUMMARY
Centripetal acceleration is the acceleration experienced by an object moving in a circular path, directed towards the center of the circle. Its magnitude is calculated using the formula a = v²/r, where v represents the object's velocity and r is the radius of the circular path. This acceleration occurs even when the object's speed remains constant, as the direction of the velocity vector changes. Examples include a car navigating a circular track and a ball being swung on a string, both demonstrating the necessity of centripetal force to maintain circular motion.
