Exit Objective 7.7A ; Contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp, or standing still by presenting lab posters and calculating work.

5 Lab- Ramp /No Ramp Procedure: 1. One student needs to volunteer a shoe for this activity. 2. Attach the shoe to a spring scale. 3. Using the spring scale, lift the shoe into the air so that it is the height of 0.5 m. Record the amount of force needed to lift the shoe and the height the shoe was raised. 4. Build an inclined plane (ramp) with the boards to reach a height of 0.5 m. Use as many books as necessary. Record the length of the inclined plane and height of the inclined plane (ramp). 5. Attach the spring scale, and pull the shoe up the inclined plane (ramp). 6. Record the amount of force it took to move the shoe. 7. Repeat steps 3–5 again.
