Centripetal acceleration (also called normal acceleration), is the acceleration that determines the change of direction of velocity in bodies rotating or moving along curved trajectories. This acceleration is called centripetal because it is always directed towards the center of rotation.
Angular velocity is a measure of rotational velocity. It is defined as the angle rotated by a unit of time and is designated by the Greek letter ω. Its unit in the International System is the radian per second (rad/s).
