Draw the direction and magnitude of all the forces acting on the block of mass m when it is:
(a) Stationary on the incline
(b) Sliding down the incline with velocity, V
(c) Sliding on a concave surface with velocity, V.
All surfaces have friction.

Please describe the forces invovled - starting with gravity, which acts downward. Consider friction - in which direction does is it oriented?

If something is not moving, what does that tell one about the net forces?

What forces are normal? What forces are tangential?
