                            Define 1 J of work.     

    Answer:

                                                         Work done = Force x Displacement If force, F = 1 N and displacement, s = 1 m, then the work done by the force will be 1 Nm or 1 J. Thus, 1 J is the amount of work done on an object when a force of 1 N displaces it by 1 m along the line of action of the force.
