A rock is dropped from a tower free falling with the influenceof gravity, neglect air resistance.
true or false?
1. as rock falls, the net work done by all the forces acting on therock is 0 J.
2.The kenetic eneergy increases by equal units over equaldistances.
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 eachsecond.
7. The rock will gain speed for each meter through which itfalls.
8.The amt of momentum the rock gains will be proportional to theamt of potential energy it loses.
9.The rock will gain an equal amt of kenetic energy during eachsecond.
10. The rock will gain momentum for each meter through which itfalls
