1. you only have a couple of numbers. What are you going to do with them?
what is mechanical advantage? The ratio of force produced to force exerted, right?

2. (question 1) B, (mechanical to gravitational)
(question 2) D, (H)
(question 3) - 1 is gravitational potential energy, 2 is sound energy, 3 is electromagnetic energy and 4 is mechanical energy
(question four) C, (kinetic)
(question five) D, (4)
(question six) C, (The gravitational potential energy at point A is four times as large as that at point B.)
(question 7) A, 360 J
