give an example in which force does negative work​

Answer 1

Negative work follows when the force has a component opposite or against the displacement. 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.
