A force acting on an object does NO work if:
**the force is not in the direction of the object's motion.**
In physics, work is defined as the product of the force applied to an object and the displacement of the object in the direction of that force. If the force is perpendicular to the direction of motion or has no component in the direction of the motion, then the work done is zero.
