A level physics

Just a general question,
If something is MOVING UP an inclined plane,then that object has to do work AGAINST gravity,and when something moves DOWN an inclined plane, GRAVITY does work on that object.
Am I correct?
Please correct me if I'm wrong

What object are you referring to?

I would recommend that you do not generalize the situation.

An object with mass moving up a plane means something is providing the necessary GPE. If something is moving down a plane then it depends. Certainly some GPE is recovered but consider an object on a steel rail with a coil being pulled down the slope against linear induction, most of that work would not necessarily come from gravity.
As the poster above said in their very succinct reply, you need the detail.

In this situation, you are ok to say so. :smile:
There are some subtle points which I don't think are necessary at this level.
