When the body moues in the direction of the force.
When the body moues in the direction opposite to the
force
when the body moues at an
to the direction of
force

Answer:
1) The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter.
2) Thus, work done by a force acting on a body is equal to the magnitude of the force multiplied by the distance moved in the direction of the force.
3) As work done is given by formula F×s and here force and displacement is in opposite direction. Hence, the work is negative work done i.e, against the direction of force.
4) As work done is given by formula F×s and here force and displacement is in opposite direction.Hence, the work is negative work done i.e, against the direction of force.
