0 work means when no work is done  eg : when a weight lifter lifts weight there he dose not do any work 

Posted by Subham Bakshi(student)

why he doesnt do any work he is lifting the rock which is against the force of gravity

Posted by Gayathri Jahan ...(student)

i am suppose to say that when force is applied and the object does not displaces it  then 0 work is done

Posted by Rakshak H(student)

W=s.F.cosx . when a person tends to change the position of the object but there is no displacement by the applied force then the work done by the applied force on the object is 0 . 

Posted by Mr. Poet (student)

Friend the work done is zero in three conditions :

1) When there is no displacement

2) When the displacement is normal to the direction of force. Ex- A collie carrying a Load in his head.
