Question

4. Why the work is said to be negative when force and displacement are in opposite directions​

Answer 1

Answer:

Gravity does negative work here because gravity goes in the opposite direction as the displacement. If the crate is moving upwards at a constant velocity, what is the work done by the tension in the rope as it is hoisted up 10 meters? ... This is positive work. The tension force is in the same direction as the movement.
