Energy

• Ability to do work.
• Potential Energy is any form of stored energy.
• Gravity
• Springs
• Kinetic Energy is energy in motion.
• Falling Apple
• Moving Vehicle

4
Energy

• There are 3 different categories of Energy.
• Exhaustible / Non-renewable
• Renewable
• Inexhaustible

5
Exhaustible / Non-Renewable

• Examples of Nonrenewable Energy
• Petroleum Based Fuels
• Nuclear Energy

6
Renewable

• Renewable Energy is sometimes called
  Bio-conversion.
• Examples of Renewable Energy
• Human Energy
• Wood
• Alcohol / Methanol / Bio-diesel
• Trash?

7
Inexhaustible Energy

• Examples of Inexhaustible Energy
• Wind
• Hydro / Wave
• Solar
• Geo-Thermal
• Cold Water?

8
6 Forms of Energy Their Uses

• Thermal
• Chemical
• Mechanical
• Radiant
• Electrical
• Nuclear

• Manufacturing
• Batteries / Food
• Motion
• Solar Heat
• Movement of electrons
• Fission / Fusion

9
Conservation of Energy

• Law of Conservation of Energy - Energy cannot be
  created nor destroyed, however it can be
  converted from one form to another.
• Second Law of Thermodynamics - No energy system
  can be a 100 efficient.

10
Energy Measurements

• Joule
• BTU
• Calorie

11
Work

• Work is the application of force that moves an
  object a certain distance.
• Work can be calculated through the following
  equation
• Work Force Applied x Distance

12
Power

• Power is the amount of work being done over a
  period of time.
• It is a measure of how quickly work is/can be
  done.
• Energy is useful ONLY when it is converted into
  power.
• Power Force x Rate

13
3 Components of Power

• Control
• Transmission
• Storage

14
Control of Power

• To use power effectively, we must be able to
  control it.
• Controlling power enables one to start, stop, or
  change direction.

15
Energy Transmission

• Movement of energy within or into another energy
  system.

16
Mechanical Advantage

• Mechanical Advantage is an increase in force
  provided by a machine.

17
Simple Machines

• Lever
• Pulley
• Gear
• Incline Plane
• Wheel and Axle

18
Fluid Power

• Hydraulics Systems are those that control and
  transmit energy through liquids.
• Pneumatic Systems are those that control and
  transmit energy through gases.

19
Newtons Laws of Motion

• Newton's First Law A body of mass in a state of
  rest tends to remain at rest and a body or mass
  in motion tends to remain in motion, unless acted
  upon by another force.

20
Newtons Laws of Motion

• Newton's Second Law An unbalance of force on a
  body tends to produce an acceleration in the
  direction of the force.

21
Newtons Laws of Motion

• Newton's Third Law For every acting force there
  is an equal and opposite reacting force.

22
4 Energy Systems

• Mechanical
• Fluid
• Electrical
• Thermal

23
How an Automobile uses Energy

• Mechanical
• Transmission
• Gears / Cams
• Brake Rotors
• Fluid
• Engine Coolant
• Lubricating
• Brake Fluid
• Fuel Pump

• Electrical
• Starting
• Lights
• Spark Plugs
• Fuel Pump
• Climate Control
• Thermal
• Engine Cooling
• Climate Control
