force does require motion.

suppose you have hydraulic piston that can lift your car.

it cant lift your car unless the piston is allowed to move.

That's right. If the piston can't push harder than what the car weighs then the car won't move. That is if the piston doesn't exert enough force then the car won't move. Notice that force doesn't always cause movement. My feet pressing on the Earth exerts a force equal to my weight on the surface of the Earth. But that doesn't cause the surface of the Earth to move.

Give up Paul, go study some physics, maybe do some simple experiments, then figure out how things work.
