Best Answer

One formula that is frequently used is: friction = mu x Fn, where mu (the Greek letter mu) is the coefficient of friction, and Fn is the normal force - the force that pushes the surfaces together, perpendicular to the surface.

The coefficient of friction depends on the combination of materials; you can look it up in tables for different combinations of materials; or you can determine it experimentally.

There's no fun in playing it safe. Why not try something a little unhinged?
