Energy

energy

the ability to do work

kinetic energy

the energy of motion

potential energy

the energy of position, shape, or composition. stored energy.

mechanical energy

the sum of potential and kinetic energy

energy conversion

the change of energy from one type to another

law of conservation of energy

energy cannot be created or destroyed, only changed.

nuclear energy

the energy stored in the nucleus of the atom. a form of potential energy

chemical energy

the energy stored in the bonds between atoms. a form of potential energy

electrical energy

the energy of moving electrons. a form of kinetic energy

thermal energy

the energy of moving particles. a form of kinetic energy. NOT THE SAME THING AS TEMPERATURE!

radiant (light) energy

the energy of moving light particles (photons). a form of kinetic energy

sound energy

the energy of a vibrating object. a form of both potential and kinetic energies.

energy transfer

the movement of energy from one place to another without changing forms/types.

energy transformation

the change of energy from one type to another usually as it moves.

kinetic energy formula

KE=1/2 (mv^2) or KE= (mv^2)/2

potential energy formula

PE=mgh (when g is the acceleration due to gravity)

PE=weight x height

gravitational potential energy

The energy stored in an object based on its position above the Earth's surface.

Energy Resource

A source or supply of energy that can be used to generate electrical power to meet people's needs.

nonrenewable resource

A natural resource that is not replaced in a useful time frame.

renewable resource

Any natural resource (as wood or solar energy) that can be replenished naturally with the passage of time

fossil fuels

Coal, oil, natural gas, and other fuels that are ancient remains of plants and animals.
