Work
- Definition - Work occurs when a force is applied over a
distance.
- equation and units
- W=Fxd
- W - Joules (J)
- F - Newtons (N)
- d - meters (m)
- simple example
- aside - other units Calorie for example
- Discussion - nature of work
- confusion between work and energy
- common units
- McCulloch's theory - Work is what occurs when energy
changes from one form to another.
- Discussion about direction of force relative to displacement
- Force perpendicular to displacement direction
- Force at an angle a to the
direction of motion
- Positive and Negative Work
- Positive - force in same direction as displacement
- Negative - force opposite in direction to
displacement
