1. Type of Energy

2. Electrical Energy
• Can be generated easily from other form
of energy
• Passed quickly through electric conductor
• Can be changed to other type of electric
easily

3. Heat Energy
• Can be felt
• Flow from a region of high temperature to
a region of low temperature
• Can be transmitted through a vacuum

4. Sound Energy
• Can be heard
• Produced by strong vibration of molecules
• Cannot pass through a vacuum

5. Light Energy
• Can be seen
• Can pass through a vacuum
• The speed of light is equal to the universal
speed limit; light travel the fastest
• The light ray can be bent if there is a
mirror

6. Kinetic Energy
• Energy in a moving object
• The higher the speed and the mass, the
higher the kinetic energy

7. Potential Energy
• Stored energy
• Gravitational Potential Energy
• Elastic Potential Energy

8. Gravitational Potential Energy
• Gravitational potential energy increase
when the object is at a higher altitude

9. Elastic Potential Energy
• Energy stored in a stretching elastic object

10. Chemical Energy
• Energy stored in substance
• Can be easily changed to other forms of
energy

11. Nuclear Energy
• Energy stored in the nuclei of atom

12. Summary
• Electrical energy is easily generated . It pass
quickly through electric conductor. Heat
energy flow from a region of high to low
temperature. Strong vibration of molecule
form sound energy. Light energy travel the
fastest and can be bent .Kinetic Energy is
energy in moving object. Amount of kinetic
energy is determined by the speed and mass.
Potential energy is stored energy. The
object’s altitude determine the amount of
gravitational potential energy. Elastic
potential energy is elasticity stored in an
elastic object. Chemical energy is energy
stored in substance. Nuclear Energy is energy
