Answer:

POSITIVE WORK :the work done on an object is said to be positive work when force and displacement are in same direction.

example: When an object moves on horizontal surface,force and displacement acts in forward direction. So,work done is positive.

NEGATIVE WORK:The work done is said to be negative work when force and displacement are in opposite direction.

example: When an object is thrown upwards,the force CTS in downward direction whereas displacement acts in upward direction.

ZERO WORK:The work done is said to be zero work when force and displacement are perpendicular to each other or when either force or displacement is zero.

example: When we hold an object and walk,the force acts in downward direction whereas displacement acts in forward direction.
