Conservation of Matter & Energy
| Question | Answer |
|---|---|
| Neither Matter nor Energy can every be created of destroyed. | Law of Conservation of Matter & Energy |
| Kinetic Energy | Energy of Motion |
| Potential Energy | Stored Energy due to position |
| Energy moving from one object to another | Transferred Energy |
| Energy chaning from one type to another | Transformed Energy |
| Radiation | Transfer of energy in straight lines by electromagnetic waves. |
| Conduction | Transfer of energy by collision of particles in matter. |
| Convection | Transfer of energy in a fluid (liquid or gas) by the movement of heating & cooling particles. |
| Transformation | When energy changes from one type to another. |
| Energy that comes from the Sun? | Electromagnetic...light & heat |
| Energy produced by fire? | heat & light |
| Energy of a falling rock? | Gravitational Kinetic energy |
| Energy stored in a cookie? | Chemical energy |
| Energy produced by your vocal chords? | Sound energy |
| Energy of a car traveling down the road? | Mechanical kinetic energy |
| The transfer of energy that occurs when a force makes an object move. | Work |
| Word = ? | Force x Distance |
| A push or a pull? | Force |
| Work done in the same direction as the object's motion. | Positive work |
| Negative Work? | Work done on an object in any direction not identical to the object's motion. |
| Power = ? | Work / Time |
| Work accomplished in less time takes more...? | Power |
| Thermal Kinetic Energy? | Heat |
| Measurement of heat? | Temperature |
| SI temperature scale? | Celcius |
| Absolute temperature scale - theoretically all particle motion stops. | Kelvin |
