State kepler's three laws of planetary motion

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                                         : )

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

3. dark matter

empty space could also be a simple vacuum
