1. Explain how he would calculate how much force to use to lift the refrigerator straight up into a truck *

2. Joe starts thinking about easier ways to get it in the truck and remembers he has some wood that he could use to make a ramp. How could he calculate the minimum force needed to push it up the ramp? *

3. Use the simulation to check your ideas by running experiments with different objects at several angles. Make a data table including several trials with the calculations *
