If I were to drop a penny from empire state building it would do more damage than if i dropped it from standing distance. Why? F=MA. neither the penny's acceleration nor mass change when its falling so the forces on both pennies should be the same. The only solution i could come up with is that the acceleration comes from the deceleration caused when the penny hits the ground which would be bigger than the acceleration due to gravity and would be based on the time spent falling or in other words the height . am i correct?
