How much work is done in ploughing the length of the field? A pair of bullocks exerts a force of 140 N on a plough. Solution : 1J is that work which is done when a force of 1N is applied on an object and it moves a distance of 1m in the direction of force

Write an expression for the work done when a force is acting on an object in the direction of its displacement. Solution : Work is done when a force acts on an object and displacement occurs in the direction of force. Since Work (W)= Force (F) x displacement (d) Let us take it that the force acts on the object through the displacement. The displacement is, say 8 m, in the direction of the force.
