**There are three types of acceleration in general: absolute acceleration, negative acceleration and acceleration due to change in direction.** Acceleration is defined as the rate of change of velocity.

Acceleration can be also categorized depending on whether the motion of the object is linear or angular. For objects with a linear motion, acceleration can be divided into two types: average and instantaneous. For objects with angular motion, it can be divided into three types: centripetal, tangential and angular acceleration. Since acceleration depends on velocity, which has both magnitude and direction, the acceleration of an object can change depending on a change of magnitude, a change in direction or change in both direction and magnitude.
