Energy for Movement
| Question | Answer |
|---|---|
| Energy | The ability to do work |
| Work | When a force moves an object |
| Mechanical energy | Matter in motion or with the potential of motion. Can be classified as kinetic or potential energy |
| Kinetic energy | The energy of motion. Related to an object's speed; the faster it moves, the more it has |
| Potential energy | Stored-up energy that can be released to cause motion because of its position or condition |
| Law of conservation of matter | Matter can be neither created nor destroyed |
| Law of conservation of energy | Energy can be neither created nor destroyed |
| Albert Einstein | German physicist that showed that under certain extraordinary conditions mass is not conserved; mass can be converted into energy and energy into matter |
| Law of conservation of mass and energy | The total of the mass and energy of the universe always remains the same |
| Theory of special relativity | E=mc squared. The conversion of a small amount of matter can yield a very large amount of energy |
