Gerald is fishing. He uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish.

Which statement accurately describes the densities of these two items?

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                                         : )

what is the actual question though?
