1. Energy Systems
An energy system is a method by which energy is transferred and work is done.
There are four basic types of energy systems:
Mechanical
Fluid
Electrical
Thermal

2. Mechanical Systems In a Mechanical System what is the prime mover?
Force
What is moving in a mechanical system?
The object that had the force applied to it
What opposes motion (movement) in a mechanical system?
Friction

3. Fluid Systems What is a Fluid System? (Examples) Hydraulic, Pneumatic
In a Fluid System what is the prime mover?
Pressure
How does pressure relate to force?
P = F/A
What is moving in a fluid system?
Molecules
What opposes motion (movement) in a fluid system?
Viscosity

4. Electrical Systems In an Electrical System what is the prime mover?
Voltage (potential difference)
What is moving in an electrical system?
Electrons
What opposes motion (movement) in an electrical system?
Resistance
What is friction called in an electrical system?

5. Thermal Systems In an Thermal System what is the prime mover?
Thermal Gradient (difference in temperature)
What is moving in an thermal system?
Molecules of air, electrons
What opposes motion (movement) in an thermal system?
Insulation
What is friction called in an thermal system?
