Answer:

Positive work is said to be done when the force acting on a body produces a displacement in the direction of the force. Negative work is said to be done when the force acting on a body produces a displacement opposite to the direction of the force

Step-by-step explanation:

When the displacement of the body the in the direction of the force then the work done is positive. For example :- a man pushing a car in a straight path.

When the displacement is in a direction opposite to the direction of the force then the work done is said to be negative. For example :- work done by the friction.
