Hey!!!...here is ur answer
1. Direction of force and direction of displacement is same..means the body moves towards the direction of force.And the work is called positive work.
2. when angle is 90° then the direction of force and direction of displacement is perpendicular to each other....means the body moves towards the perpendicular direction of force.And the work is called zero work.
3. when angle is 180° then the direction of force and direction of displacement is opposite to each other...means the body moves towards the opposite direction of force.And the work is called negative work.
Hope it will help you
