There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.

Imagine a racecar that's traveling in a straight line. If it changes velocity (speeds up or slows down), then it's accelerating. This type of acceleration, with only a change in velocity but no change in direction, is called linear acceleration. If the racecar is instead driving around a circular track at a constant speed, only its direction is changing. This kind of acceleration is called centripetal or radial acceleration. If the car changed both its velocity and its direction, then we would have angular acceleration.
