Question

When do we say that work is done
?

​

Answer 1

Answer:

when Some force acts and the place is changed then work is done because Work = F×D

if u apply force and no distance is covered then no work is done for work the distance should be changed from Its original position to new position.

if u apply force on a truck stationary then no work is done because your force is not much to move the truck and no distance is changed therefore no work is done
