Energy and Energy Transformations
Term | Definition |
---|---|
law of conservation of energy | -energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed |
friction | a force that resists the sliding of two surfaces that are touching |
temperature | the measure of the average kinetic energy of the particles in a material |
heat | the movement of thermal energy from a region of higher temperature to a region of lower temperature |
conduction | the transfer of thermal energy by collisions between particles in matter |
radiation | the transfer of thermal energy by electromagnetic waves |
convection | the transfer of thermal energy by the movement of the particles from one part of a material to another |
vaporization | the change of state from a liquid to a gas |
thermal conductor | a material in which thermal energy moves quickly |
thermal insulator | a material in which thermal energy moves slowly |
