work done by an object is defined as the magnitude of force multiplied by the displacement done by an object.si unit is joule .two factors on which magnitude of work depend are force and displacement. work done is positive when we push table and it move in the direction of applied force. work done is negative when frictional force acts on a body as it is in opposite direction.
