In symbols, average acceleration a− is a−= ΔvΔt=vf−v0tf−t0. The SI unit for acceleration is m/s2 . Acceleration is a vector, and thus has a both a magnitude and direction. Acceleration can be caused by either a change in the magnitude or the direction of the velocity. Instantaneous acceleration a is the acceleration at a specific instant in time. Deceleration is an acceleration with a direction opposite to that of the velocity.

According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force.

If the initial velocity is +15.0 m/s and 5.0 s is required to slow down to +5.0 m/s, what was the car’s acceleration? Average acceleration is the rate of change of velocity, or the change in velocity per unit time. If an automobile slows from +26 m/s to +18 m/s in a period of 4.0 s, what was the average acceleration?

The acceleration due to gravity gives rise to a common (non-SI) unit of acceleration, also called the g :

The SI unit for acceleration is meters per second squared. Acceleration can be caused by a change in the magnitude or the direction of the velocity, or both. Instantaneous acceleration is the slope of the velocity-versus-time graph.
