Acceleration • Acceleration is a change of velocity over a period of time
expressed by
the equation below.

• Acceleration is equal to the change in
in meters per
second every second.
Change in velocity is determined by subtracting the
velocity
(the starting velocity) from the final velocity (ending velocity).
• To get acceleration, you divide change in velocity by
The unit for acceleration is
which is usually written as m/s2
