Answer 2

Answer:

positive work : When force and displacement are in the same direction, the work performed on an object is said to positive work.

Example : When a body moves on the horizontal surface , force and displacement act in the farward work . The work is done in this case known positive work.

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 downward direction whereas displacement acts in the farward direction ..........
