Question

Say I shot a block up a slope. Would the magnitude of the work change if my slope had two different angles? Or several? Or was a curve?

Answer 1

Like this:
Or like this:

Answer 2

yes if the angle changes

Answer 3

Work = Force x distance x cos θ

As θ increases from 0° to 90°, the magnitude of the work done decreases. When θ = 0°, all the force applied is in the direction of motion and the object is displaced, then work = force x distance. When θ = 90°, all the force applied is perpendicular to the direction of motion, and the work done is zero. Of course, work done can also equal zero, if the object does not move, even if all the applied force is in the the direction of intended motion.

Answer 4

only if you considered friction, otherwise W= mgh: same for any ramp angle or set of ramp angles if the height of the ramps are the same.
