please explain zero work once again..not able to understand it at all..in a simple language..?
suppose u push a rock from moring to eveing the rock does not move then 0 work is done

In physics, we say work is done when force applied to an Object causes displacement of object.
When force applied on an object doesn't cause displacement of object we say that no work or zero work is done. Or you can say when displacement of object is zero then work is zero(W=Force ? displacement).
If I carry an object A from place X to Y and carry it back to X, the displacement and work done will be zero in physics. Since the object didn't move from its original position.

ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero. example: When we hold an object and walk,the force acts in downward direction whereas displacement acts in forward direction.
