It is the movement of liquid along a surface of a solid caused by the attraction of molecules of the liquid to the molecules of the solid. Let's simplify. A liquid, like water, going up a narrow tube naturally is not considered as a typical. Since, water and other liquids in general flows with the gravitational forces, it requires specific circumstances and physical effect to flow against the forces of gravity.…show more content…
In fact, such forces can be greatly reduced, but they can never be completely eliminated without expending additional energy. A prime example is the superconductive metals, whose electrical resistance disappears completely at low temperature, usually somewhere around 20 K. Unfortunately, the energy required to maintain the low temperature exceeds the work that results from the superconductive flows so our purpose of getting a motion which does not need any outside push to remain in motion is not full filled so this type also fails to give us a perpetual machine in real
