Define positive negative and zero work done

1.	Define positive negative and zero work done
Answer» ne can also be positive or NEGATIVE. ... Work done by a FORCE is positive if the applied force has a component in the DIRECTION of the displacement. When a body is falling down, the force of gravitation is acting in the downward direction. The displacement is also in the downward direction..Work is zero if applied force is zero (W=0 if F=0): If a BLOCK is moving on a smooth horizontal surface (frictionless), no work will be done. ... Work done is zero when displacement is zero. This happens when a man PUSHES a wall. There is no displacement of the wall. Thus, there is no work done.
