| energy | the ability to do work |
| forms of energy | light, heat, sound, and motion |
| categories of energy | potential and kinetic |
| kinetic energy | energy of MOTION |
| potential energy | stored energy and the energy of position or condition |
| thermal (heat) energy | vibration and movement of the atoms and molecules in a substance - internal energy |
| conduction | When heat travels from ONE OBJECT or substance directly TO ANOTHERr creating heat as the atoms actually come in contact or touch each object. |
| example of conduction | A flame from a burner touches a pot sitting on top of the flame. The pot gets hot and water inside the pot is heated by the hot, metal of the pot. The food inside the pot becomes hot or cooks because of the water in which it is sitting. |
| convection | This heat uses the movement of HOT AIR to heat a space whether it be in a room from a heateror in a convection oven. The heat energy is focused on the air inside of the space where it is superheated and rises. As the air coold, it sinks and falls and then is reheated to circulate around again. |
| radiant heat | Heat that travels in a straight line (like a sun's ray) from the source of the heat to the person or thing being heated |
| campfire, the sun, a stove, electric heater | examples of RADIANT heat |
| How is standing around a campfire a good example of radiant heat? | The air may be cold, but the heat travels from the fire to you, warming you. |
| to conduct heat | is to have it FLOW THROUGH a substance or an object strongly and efficeintly - object to be cooled |
| to reflect heat | BOUNCE AWAY from where it is aimed or where it is headed |
