Question

define negative work an give example​

Answer 1

When a body moves on the horizontal surface, force and displacement act in the forward path. ... Negative work: Negative work is performed if the displacement is opposite to the direction of the Force applied. Example: Work was done the gravity on a rocket going perpendicular upwards.

Negative work removes or dissipates energy from the system. Two examples: In pulling a box of books along a rough floor at constant velocity, I do positive work on the box, that is I put energy into the system. The force of friction opposes the displacement (always), and does negative work.

Answer 2

Answer:

negative work is the force has component opposite or against the displacement.

Explanation:

example ... I do positive work on the box .
