| Heat | thermal energy moving from high temperature to low temperature |
| thermal equalibrium | when two objects touching each other are at the same temperature |
| conduction | the transfer of thermal energy because of collisions between particles( can happen in solids liquids and gases) |
| thermal conductor | a material that thermal energy can move through quickly |
| thermal insulator | a material that thermal energy moves through slowly |
| convection | the transfer of thermal energy from one part of a material to another (can happen in liquids and gases) |
| convection current | the rising and sinking of the particles in a loop or circular motion |
| radiation | the transfer of thermal energy through electromagnetic waves (can travel through solids liquids gases and the vacuum of space) |
| waste energy | thermal energy that cannot be used |
| friction | the force that resists when two object rub against each other |
| Law of Conservation of Energy | energy can be transformed but cannot be created or destroyed (superman) |
| mechanical energy | the sum of potential and kinetic energy in a system |
| sound energy | the energy sound carries in waves |
| thermal energy | the sum of kinetic and potential energy in an object |
| electrical energy | energy carried in electrical currents |
| radiant/light energy | energy that electromagnetic waves carry |
| nuclear energy | energy release from the nucleus of an atom |
| work | is the force that is transfered when an object moves in the direction of the force |
| elastic potential energy | energy stored in an object that has been compressed or stretched |
| gravitational potential energy | energy that is stored in objects the higher they are moved |
| chemical potential energy | energy that is stored in between atoms that are chemically bonded |
| kinetic energy | energy due to motion that increases with speed and mass |
| energy | the ability to cause change |
