How do you find the centripetal force of an object with a mass of 5 kg and with an acceleration of 2 m/s?

Force = mass * acceleration

          = 5 * 2

Force = 10 N

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
