There are many examples where we can say no work is done according to physics few of them are
If a weightlifter lifts weight And holds it for a long time we can say no work is being done because there is no displacement. So there no work is done.
One another example could be of pushing a Wall in pushing Wall after some time you will feel tired but in actuality according to physics, no work is done because there is no displacement.
In simple, we can say according to physics if force is applied but no displacement occurred there is no work done
