| The energy of an object that is due to the objects motion? | |
| The energy that an object has because of the position, shape, or condition of the object? | |
| weight x height? | |
| The amount of work an object can do because of the objects kinetic and potential energies ? | |
| All of the kinetic energy due to random motion of the particles that make up an object.? | |
| The energy of a compound that changes as its atoms are rearranged? | |
| The energy of moving electrons? | |
| Caused by an objects vibrations (waves)? | |
| Energy that is produced by the vibrations by electrically charged particles? | |
| The energy that comes from changes in the nucleus of an atom? | |
| A change from one form of energy to another ? | |
| The stored energy when it is wound up like a rubber band? | |
| Uses light energy to make new substances that have chemical energy ? | |
| A force that opposes motion between two surfaces that are touching? | |
| Energy cannot be created or destroyed? | |
| This is impossible because there is always thermal energy caused by friction ? | |
