Energy Transfer One (Step One): Roll back has potential energy at top of ramp, rolls down ramp, Potential Energy converts to Kinetic Energy.
Energy Transfer Two (Step Two): Car hits metal ball atop bolt, Kinetic Energy converts to Kinetic Energy or an Elastic Collision.
Energy Transfer Three (Step Six): Golf ball has potential energy before pin is pulled and is at rest. After pin is pulled, ball rolls down ramp. Potential Energy is then converted to Kinetic Energy.
Energy Transfer Four (Step Nine): Golf Ball is at rest and has potential energy. Measuring cup dislodges ball and pushes ball off ramp converting Potential Energy to Kientic Energy.
