hii friend
work done:
work is said to be done when a force F acts on an object and object moves through a distance or there is displacement in the direction of the force.
i.e work done =F×S
work done can be zero when any of these things happen:-
1.) when the force applied is zero.
2.) when displacement is zero.
3.) if cos is 90° then work done is zero .
w=FScos
ex. -->a girl pushing a heavy rock.
hope this helps
