|Energy||The ability to do work|
|Potential Energy||Stored energy and the energy of position.|
|Kinetic Energy||The energy of motion.|
Stored Mechanical/Elastic Energy
|The energy stored in an object by applying a force.
Compressed springs and stretched rubber bands are examples.
|Atomic/Nuclear Energy||The energy stored in the nucleus of atoms. Energy is generated when the nucleus of atoms join together or split apart.|
|The energy stored in matter that is released during a chemical change.
(Ex. Biomass, petroleum (oil), natural gas, and food)
|Gravitational Energy||The energy of position or place. (Ex. Rock on a hill)|
|Heat/Thermal Energy||The energy related to heat and the temperature of matter.|
|Electrical Energy||The energy of electrically charged matter. (Ex. Lightening)|
Electromagnetic energy that travels in vertical (transverse) waves.
(Ex. Visible light, x-rays, gamma rays, and radio waves)
|The sum of potential and kinetic energy in an object that is used to do work; this energy has potential and kinetic energy.
Lifting a hammer (potential energy) and then hitting a nail into wood (kinetic energy) is an example of this type of energy.
|The movement of energy through substances in longitudinal (compression/rarefaction) waves.
Sound is produced when a force causes an object or substance to vibrate; the energy is transferred through the substance in a longitudinal wave.
|Law of Conservation of Energy||Energy can neither be created or destroyed, it just changes form.|
|Energy Conversion||The process of changing from one form of energy into another|
|Force||A push or pull; all forces have both size and direction.|
|Balanced Force||When the forces applied to an object produce a net force of zero; balanced forces DO NOT cause any change in motion.|
|Unbalanced Force||When the net force of an object is NOT zero; it takes an unbalanced force to produce any change in motion (starting or stopping).|
|Speed||The rate at which an object moves; speed depends on the DISTANCE traveled and the TIME taken to travel that distance. Speed=distance/time|
|Velocity||The speed of an object in a particular direction.|
|Conduction||Heat transfer through direct contact; usually a solid.|
|Convection||Heat transfer through a convection current; gas or liquid.|
|Radiation||Heat transfer through electromagnetic waves.|
|Pulley||A simple machine that uses a grooved wheel and a rope to raise, lower or move a load.|
|Inclined Plane||Slope used to lift heavy objects.|
