Explanation:
work is done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force we define work to be equal to the product of the force and the displacement.
W = F × s
1J = 1N × 1m
J =Nm
where joules (J) is the unit of work.
