TYPES OF ENERGY J

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. J Gravitational potential energy Stored energy Sound energy Electrical energy Kinetic energy Chemical energy Elastic potential energy Energy transfer

THE LAW OF CONSERVATION OF ENERGY

A light bulb changes electrical energy into ……… and ………… energy.

The car changes …………… energy into ………….. energy and ………………energy.
