| chemical energy | energy that is stored in the particles of matter (H20, food, batteries,plants,ect.) |
| mechanical energy | energy of motion or moving parts (bicycle, wind turbine, ocean waves, wind, arms and legs) |
| radiant energy | energy that travels on invisible waves (sunlight(solar energy), heat from fire, x-rays, microwaves) etc. |
| thermal energy | the energy that all matter has because its particles ( atoms,molecules) are in motion. |
| electrical energy | the energy that comes from moving electrons (can be static or current.) |
| potential energy | energy that is stored and ready to be used |
| kinetic energy | energy that is working or in motion |
| law of conservation of energy | energy cannot be created or destroyed, but it can be changed (transformed, converted) to a different form or transferred from one object or another. |
| conserve | to save. in respect to energy, it means that energy is never created or destroyed, but always stays the same amount, even when it is transferred or transformed. |
| transfer | to move something from one place or one object to another-the same type of energy can passed along from one object to another. |
| transform or convert | other words that mean the same thing as the word change. heat-the transfer or flow of thermal energy from a warmer object to a cooler object. |
