Energy
| Word | Definition |
|---|---|
| Energy | Ability to do work |
| Joule | Unit in which energy is measured |
| Work | involves a change in movement |
| K.E. | energy of motion |
| P.E. | energy of position |
| G.P.E. | depends on height above the earths surface |
| Heat Energy | internal motion of particles of matter |
| Mechanical Energy | energy of motion (not K.E.) |
| Specific Heat | ability of a substance to absorb heat |
| wavelength | the distance between 2 consecutive crests or troughs |
| Conduction | heat transferred through an object or from one object to another |
| Convection | heat transferred, takes place if liquids and gases as molecules move in currents |
| Radiation | transferred by convection, takes place in the form of vision line |
| Law of Conservation of Energy | energy that can be nor created nor destroyed by ordinary means |
| Wave | a disturbance that transfers energy through matter or space |
| Crest | the highest point of a transverse wave |
| Trough | the lowest point of a transverse wave |
| Amplitude | the distance between rest position to the crest or trough |
| Frequency | number of waves or complete cycles per unit of time |
| Absolute Zero | All molecular motion stops |
| velocity | _______ has a better effect than mass on K.E. |
| P.E. | _________ depends on weight and height |
| K.E. | __________ depends on mass and velocity |
| Warmer | Air molecules would move faster on a __________ day |
| Increase | The addition of heat indicates a _______________ in temp. |
| Decrease | The removal of heat indicates a _____________ in temp. |
| Longitudinal | Sound waves are an example of _________ waves |
| Decreases | If wavelength ____________, frequency increases. |
| High | Short Wavelength=_______ frequency |
| Suspension Length | the __________ has the greatest effect on a pendulum |
