5. Why does it take more effort to make a bowling ball accelerate 25 m/s2 than to make a tennis ball accelerate 25 m/s2?

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                                         : )

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

d) physical means can be used to separate the components of air.
