Answer:
WORK DONE ON A BODY IS THE PRODUCT OF FORCE IN THE DIRECTION OF DISPLACEMENT AND DISPLACEMENT.
WORK ONLY HAS MAGNITUDE AND NO DIRECTION.
FORCE applied IN the direction of displacement × displacement = POSITIVE WORK DONE
FORCE applied OPPOSITE to the direction of displacement × displacement = NEGATIVE WORK DONE
FORCE applied PERPENDICULAR to the direction of displacement × displacement = ZERO WORK DONE
