A rightward force is applied to a 17kg object to move it across a rough surface with a rightward acceleration of
3m/s/s. THe coefficient of friction between the object
and the surface is 0.5.
Use the diagram to solve for Fgrav, Fnorm, Fapp, Ffrict
and Fnet

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                                         : )
