text: Acceleration is NOT velocity divided by time, people are crazy and they will make you fail your final ;)  Acceleration is the change in velocity divided by the change in time.  If velocity is 7m/s and the time is 7/s the acceleration is NOT 1m/s^2 like they represent above.  That would only be true if the initial velocity was 0 and the acceleration was known to be constant... If you are told that a car is traveling at 7m/s for 7s the acceleration is 0... but if you simply put v/t you would get 1... \n\nVelocity is defined as distance per unit of time.  Acceleration is the change in velocity per unit of time.
