TYPES OF ENERGYJ

• The energy an object has because it is moving.

• Vibrating objects are sources for this energy.• Forms of energy that are waiting to be used.• Food is an example of this.• This energy is available every time a current

flows.• Winding up a spring will give it this type of

energy.• One type of energy changes into another type

of energy.• The energy an object has when it is high up.
