Aball that has a mechanical energy of 65 j has 12 j of kinetic energy. the ball has j of potential energy.

53 J

Explanation:

The mechanical energy of an object (ME) is equal to the sum of the kinetic energy (KE) and the potential energy (PE):

In this example, the ball has mechanical energy ME=65 J and kinetic energy KE=12 J, therefore we can re-arrange the equation to calculate its potential energy:

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
