Answer:
Positive work: when force and displacement are in the same direction, the work performed on an object is said to be positive work.
Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.
Negative work: Negative work is performed if the displacement is opposite to the direction of the Force applied.
Example: Work was done the gravity on a rocket going perpendicular upwards.
Zero work: When force and displacement are perpendicular to each other, or when force or displacement is zero.
Example: When we hold an object and walk, the force acts in a downward direction whereas displacement acts in the forward direction.
