Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion.opposite
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
motion is the movement of an object and force is the power or work done to move the object

No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.

work
No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.

the exertion of force in a same direction; work can not be done without motion
If there is no vertical motion, then no work is done by any vertical forces.
You can measure distance traveled, energy used or work done.
If the force is perpendicular (at 90 degrees) to the direction of motion, that force does no work.
