Basically according to the physics there are three types of work done.....
1) Positive work done
When the applied force is in the direction of the motion ..then the work done is always positive ...thus it's a positive work done....basically the angle between the force and displacement should be less than 90 degrees
2) Neagtive Work done
when the applied force is opposite to the direction of motion ...then the work done is always negative...thus it's a Neagtive Work done....the angle between the force and displacement is more than 90 degrees
3) Zero work done
when the applied force is perpendicular to the direction of motion. ..then the work done is zero...thus it's zero work done...the angle between the force and displacement is 90 degrees. .....
Hope it helps.....
