Difference between positive work done and negative work done with examples
Answers
Answer:
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 but 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.
Explanation:
To give an example, when the ball was falling down, the force was in the same direction as that of the displacement, the ball speeds up. ... We saw that when the force and displacement are in the same direction, we call the work as positive. In the opposite direction, we call the work as negative.
More information:
Positive work done – The work done is said to be positive when force and displacement are in the same direction. ... Negative work done – The work done is said to be negative when force and displacement are in opposite directions.

Answer:
In physics positive and negative signs are used to describe the direction of bodies. So positive work done means that the work is done in the positive direction like positive x axis and the negative work done means that the direction of work is in the negative x axis.
