There is gravitational force on the Earth from the Sun, and a gravitational force on the Sun from the Earth. Which pulls harder?

They both pull the same amount. For every force there is an equal and opposite force.

Explanation:

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
