PE & KE Conversions. Remember. Potential Energy. Kinetic Energy. When it IS MOVING. Has the POTENTIAL to move but isn’t moving yet. It’s building up energy to move but there is no motion going on yet.
When it IS MOVING
Energy is converted to KE (kinetic energy) as the ball moves faster and faster as it falls.
Example #3: Pendulum
½ PE ½ KE ½ KE ½ PE
