Work and Energy (Chapter 6)

Objectives

1. Distinguish between work in the scientific sense as compared to the colloquial sense.

2. Write the definition of work in terms of force and displacement and calculate the work done by a constant force when the force and displacement vectors are at an angle.

3. Use graphical analysis to calculate the work done by a force that varies in magnitude.

4. Define each type of mechanical energy and give examples of types of energy that are not mechanical.

5. State the work energy theorem and apply the theorem to solve problems.

6. Distinguish between a conservative and a nonconservative force and give examples of each type of force.

7. State the law of conservation of energy and apply the law to problems involving mechanical energy.

8. Define power in the scientific sense and solve problems involving work and power.
