20. Zoom out increase the size of the ramp, and move the skater into SPACE! Press the arrow keys on your keyboard. Zoom out some more. Have fun. 21. Is there potential (mgh) energy in space? (Note that gravity goes as 1/re so there never is a location in space where the acceleration of gravity is zero, but the simulation sets gravity to zero. In your answer let me now if you are using g = 0, or the rule that g goes as 1/17) Why / Why not? 4 pts 22. Is there kinetic (Wmv.) energy in space? Why / Why not? 4 pts
