  1. Describing Motion E. A change in velocity divided by the amount of time over which the change occurs is acceleration 1. the change in velocity can be due to a change in speed, a change in direction or both. 2. when velocity is changing ￫ an object is accelerating

  2. Acceleration a Units m/s2 cm/s2 mile/s2 km/s2 mile/hour/s km/hour/s Formula • a= (vffinal - Viinitial) (tffinal - tiinitial) The final speed MINUS the beginning speed DIVIDED BY The final time MINUS the beginning time
