Do frictionless surfaces actually exist? If so, what are some examples of frictionless surfaces and how are they made?
How are these surfaces made?
Superconductors are made by cooling certain metals to incredibly low temperatures, which causes the electrons in the metal to behave differently and allows for the resistance-free flow of electricity. Other examples include ice or air hockey tables, which have a layer of air blown through tiny holes in the surface to reduce friction. Another example is magnetic levitation, which uses magnets to create a frictionless effect.
