Energy

Ability to do work

4 potential forms of energy:

Chemical, Gravitational, Nuclear, Elastic

Chemical

The energy stored in chemical bonds

ex. Food, batteries, gasoline

Gravitational 

The energy stored in an object based on its height

ex. Boulder on a cliff, kid at a top of a slide

Nuclear

Energy stored in the nucleus of an atom

ex. power plants

Elastic

Energy in materials that are stretched or compressed

ex. elastic, spring, bow and arrow

The five types of kinetic energy:

Thermal, sound, radiant, mechanical, electrical

Thermal 

Movement of particles within a substance

ex. hot iron, a lizards heat rock

Sound

Energy released by an objects vibrations

ex. drum, clapping

Radiant

Energy that travels in electromagnetic waves

Mechanical

energy of an object’s motion

ex. Wind turbines, running

Electrical

Energy of moving electric charges

ex. lightning, electrical waves

Potential energy

Stored energy

Kinetic energy

moving energy, motion energy

Law of Conservation

Energy cannot be created or destroyed

Energy transfer

energy can move or transfer from one object to another or from one substance to another. 

Energy transfer

Energy is changed from one form to another. No energy is created or destroyed.
