CHEMICAL ENERGY

Considered P. E. until used

THERMAL ENERGY

HEAT energy Anything that

holds or releases heat

Measured by TEMPERATURE

More Volume = More Energy

LAW OF CONSERVATION OF ENERGY

Begins & ends with the same amount of energy May end up being

a different type of energy

POTENTIAL ENERGY

On Ground = 0 P. E. Drawing

KINETIC ENERGY

An object IN MOTION

Examples of more K. E. Mass –

Center/Lineman Speed –

Forward/Running Back

WHEN A BALL IS DROPPED

Drawing Result P. E. changes to K. E.
