The following statements best describe energy:
- The total amount of energy in the universe remains constant. (This reflects the law of conservation of energy.)
- Energy can be converted from one form to another. (Energy can change forms, such as kinetic energy to potential energy.)
- Energy cannot be created or destroyed. (This is also a reflection of the law of conservation of energy.)
The other statements are not accurate:
- The total amount of energy in the universe changes constantly. (This is incorrect; the total amount of energy remains constant.)
- Energy cannot be converted from one form to another. (This is incorrect; energy can be converted between forms.)
- Energy can be created or destroyed. (This is incorrect; energy cannot be created or destroyed.)
