Energy | the ability to do work or cause change |
Kinetic Energy | energy that an object has due to its motion; related to the object's mass and velocity |
Potential Energy | stored energy that results from the position or shape of an object |
Gravitational Potential Energy | the potential energy related to an object's height; equal to weight x height |
Elastic Potential Energy | the potential energy associated with objects that can be stretched or compressed |
Mechanical Energy | the energy that is possessed by an object due to its motion or due to its position |
Thermal Energy | the total potential and kinetic energy that comes from heat generated by the movement of tiny particles within an object |
Electrical Energy | the energy of moving electrical charges |
Chemical Energy | a form of potential energy which is stored in the chemical bonds of atoms and molecules; it is released during chemical reactions |
Electromagnetic Energy | a form of energy that travels through space as waves |
Energy Transformation | a change from one form of energy to another; also known as an energy conversion |
Law of Conservation of Energy | the rule stating that energy can neither be created nor destroyed, but can be changed from one form to another |
