kinetic energy | the energy an object has because of motion |
electrical energy | energy that comes from electric current |
mechanical energy | the total potential and kinetic energy of an object |
chemical energy | energy that can be released by a chemical reaction |
thermal energy | the total amount of kinetic energy of the particles in a substance |
temperature | the measure of the average energy of motion of particles of matter, which we feel as how hot or cold something is |
heat | the energy that moves between objects of different temperatures |
static electricity | the buildup of electric charges on an object |
electric current | the flow of electric charges along a path |
conductor | a material that lets heat or electricity travel through it easily |
insulator | a material that does not let heat or electricity move through it easily |
circuit | a path along which electric charges can flow |
