  1. TYPES OF ENERGY J

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