Which statement best describes the benefits that would make the investment worthwhile?

fusion requires a large amount of energy and occurs in stars.
fusion produces large amounts of energy, and the fuel is found on earth.
fusion produces no radioactive waste, and the fuel is plentiful.
fusion requires little energy to begin and would continue through a chain reaction.

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                                         : )
