Question

A rock is dropped from a tower free falling with the influence of gravity, neglect air resistance.
true or false?
1. as rock falls, the net work done by all the forces acting on the rock is 0 J.
2.The kenetic eneergy increases by equal units over equal distances.
3.Kenetic energy of the rock increases by = amts. in = time.
4.Total energy of rock increases by = amts over = distances.
5.Potential energy of rock decreases by = amts. in = time.
6. rock will gain an equal amt. of momentum during each second.
7. The rock will gain speed for each meter through which it falls.
8.The amt of momentum the rock gains will be proportional to the amt of potential energy it loses.
9.The rock will gain an equal amt of kenetic energy during each second.
10. The rock will gain momentum for each meter through which it falls

Explanation / Answer

1. true for basic level physics. 2. true. 1/2mv^2=mgh. All constant 3. false. since v is going up, it takes less time to cover same distance. 4. true. It increases by 0. 5. False. 6. False. 7. true. 8. true ish. 1/2mv^2=mgh goes to v=(2gh). So in theory, it's proportional, just not directly so. 9. false. 10. True.
