Acceleration

In kinematics, acceleration is defined as the first derivative of velocity with respect to time (that is, the rate of change of velocity), or equivalently as the second derivative of position. In classical mechanics, the acceleration of a body is proportional to the resultant (total) force acting on it (Newton's second law): where F is the resultant force acting on the body, //m// is the mass of the body, and a is its acceleration.

~Samuel Phillips

When an object's velocity changes, it accelerates. Acceleration shows the change in velocity in unit time. Acceleration is measured in (m/s/s), or m/s2, which can be both positive and negative.
