Aneighbor kid is doing a science fair project about the conservation of energy. he is rolling a basketball down a ramp to show that mgh = 1/2mv^2. however, every time the experiment is run, the results show that mgh does not equal 1/2mv^2. however, if a second identical upward ramp is added, the ball very nearly goes back to its original height (so virtually no energy is being lost. perplexed, your (knowing you are taking physics) asks you what is wrong. what is your response?
