    A ball is dropped off a cliff into a canyon. A ball rests on a table. A meteor flies through space. A ball is thrown upward into the air and reaches its highest point.

    A ball resting on a table maintains its PE. A meteor flying through space essentially only has kinetic energy since PE = mgh. A ball thrown upward into the air is decreasing it's KE and increasing it's PE (mgh) on the way up...and vice-versa on the way down.

    A 1,200 kg car rolls down a hill with its brakes off and transmission in neutral. At one moment it is moving 5.0 m/s. A little later it is moving at 8.2 m/s. How much did its height change between the two times? Assume friction and air resistance have no effect on its motion. (Points : 1) 1.5 m 2.2 m 4.3 m 1.9 m
