UNIT 03 - WORK & ENERGY

EXPECTATIONS -- Before we start this unit you should:

  • Be VERY comfortable with the wolgemuthian method
  • Be VERY comfortable

UNIT I LEARNING GOALS -- At the conclusion of this part of the unit, I will be able to:

1) demonstrate understanding of work defined as force acting through a displacement

2) interpret a force vs displacement graph and calculate work by area under a curve

3) demonstrate that work occurs when energy is transferred from one form to another

3) show that the conservation of energy can be represented mathematically

4) demonstrate the relationship between potential energy and kinetic energy in ideal (no friction) situations and non-ideal (friction is present) situations.

5) use that relationship (from #4 above) to determine velocity, height and other considerations of a falling object.
