| energy | the ability to cause change |
| kinetic energy | enrgy in the form of motion |
| potential energy | stored energy |
| work | transfer of energy through motion |
| mechanical energy | total amount of potenial and kenetic energy in sytem |
| law of conservation of energy | says that energy may change form but can't be created or destryed under ordinary circumstances |
| temperature | measuer of the average kenetic energy of the particles in a simple of matter. |
| thermal energy | total energy of the particles in a material |
| heat | energy that flows from something with a higher temperature |
| thermal polution | happen when waste heatsignifigantly changes the temperature of the enviroment. |
| specific heat | is the amount of kinetic energy it takes to rise the temperature of 1 kg of a material one Kelvin |
| conduction | transfer of energy through matter by direct contact of particles |
| fluid | any material that flows |
| convection | transfer of energy by the bu;k movement of matter |
| radiation | transfer of energy in the form of waves |
| insulators | do not allow heat to move easily through them. |
| radiator | has a large surface area which heats the air around it by conduction |
| solar enrgy | energy from the sun |
| solor collector | devices that absorbe radiat energy from the sun |
| heat engine | devices that convert thermal energy into mechanical energy |
| combustion | rapid burning |
| internal combustion engine | fuel burns inside the engin in the chambers called cylinders |
| external combustion engine | when fuel is burned outside the engine |
| heat mover | a device that remove thermal energy from one location and transfers it to anotherat a different temperature |
