UNIT GOALS: s. Students will understand the difference between a quantity of
               work and the rate at which it is done.

            t. Students will explain and demonstrate principles related to
               the transmission of power.

UNIT OBJECTIVES: Upon completion of this unit, the students will be able
                 to:

1. Define energy, force, pressure, friction, work, and power.

2. Demonstrate knowledge of energy, force, pressure, work, and power, using 
   applications of levers, gears, pulleys, and shafts.

3. Describe the concept of efficiency of energy conversion and give examples 
   of energy loss.

4. Develop an awareness of the importance of safety in relation to the
   application of energy, force, pressure, friction, work, and power.

5. Define linear motion and rotational motion.

6. Explain the relationship of friction to the transmission of power.

7. Demonstrate knowledge of the transmission of power, using chains, belts, 
   gears, and shafts.

8. Develop an awareness of the importance of safety in the transmission of 
   power.
