Answer:
•Positive Work: If the force moves or displaces the object in the direction of the force. Example - when we throw a ball, the ball moves in the direction of the force.
•Negative Work: If the force moves the body ind the opposite direction of the force. Example - when we throw a ball upwards, due to gravity, it moves downwards.
•Zero Work: When the force applied does not move the body. Example - When we push a wall, it does not move.
