| nuclear energy | the energy associated with changes in the nucleus of an atom. |
| nuclear energy is a form of ________. | potential energy. |
| what causes the energy after an energy conversion to be less than the energy before the change? | friction |
| As PE changes to KE what happens to some of the energy? | some thermal and sound energy is made. |
| compare the amount of KE at the bottom of the hill with the PE at the top of the hill. | KE is not as high. the difference is the energy that becomes thermal and sound energy. |
| what is the formula for mechanical energy | KE + PE |
| law of conservation of energy- | energy cannot be destroyed or created. It can only be changed into diffrerent forms. |
