If a 50 kg student is standing on the edge of a cliff.   a.  find the student’s gravitational potential energy if the cliff is 40 m high. b. find the student’s gravitational potential energy if the cliff is 80m high

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
