1. Explain the Concepts and principles of energy and power.
Objective 7.09

2. Define Energy, Work, Power
Energy – The ability to do work.
Power – The amount of work done in a given period of time.
Work – is the application of force that moves an object a certain distance.

3. Six Major Forms of Energy
Mechanical Energy
Radiant Energy
Chemical Energy
Electrical Energy
Thermal Energy
Nuclear Energy

4. Mechanical Energy
Is often provided by the motion of a device.

5. Radiant Energy
Is the energy emitted by electromagnetic devices.

6. Chemical Energy
Energy that is stored within a substance or product.

7. Electrical Energy
Energy produced as a result of the movement of electrons through a conductor.

8. Thermal Energy
Is the name given to heat energy. Thermal cannot be seen but is generally felt.

9. Nuclear Energy Energy associated with the internal bonds of an atom.
Fission
Fusion

10. Energy Conversion Process
Mechanical Advantage
Hydraulics Systems
Pneumatic Systems
Potential Energy
Kinetic Energy

11. Mechanical Advantage
An increase in force provided by a machine.

12. Hydraulics System
Those that control and transmit energy through liquids.

13. Pneumatic Systems
Those that control and transmit energy through gases.

14. Potential Energy Is any form of stored energy.
Kinetic energy is energy in motion

15. Newton’s Law’s of Motion
1st law – a body of mass in a state of rest tends to remain at rest and a body of mass in motion tends to remain in motion, unless acted upon by another force.

16. Newton’s Law’s
2nd Law – states that an unbalance or force on a body tends to produce an acceleration in the direction of the force.

18. Law of Conservation of Energy
Energy cannot be created nor destroyed, however it can be converted from one form to another.

19. Renewable / Nonrenewable
Solar Energy
Non renewable
Petroleum based fuel

20. 2nd Law of Thermodynamics
No energy system can be 100% efficient.
