11Physics Ch-5: Work-Energy & Power

1.

In a graph of F(x) vs. x, the area under the curve represents the

energy of F(x)

work done by F(x).

impulse of F(x)

momentum of F(x)

2.

Work-energy theorem is applied for

constant force only

variable force only

both conservative forces and non-conservative force

conservative or non-conservative, external or internal forces

3.

If work done by conservative force is negative, then potential energy associated with that force should

increase

decrease

remain same

none
