Before diving into the protocol, let’s revisit the concepts behind the frictional force. First, you need to know that there are two types of frictions – kinetic friction and static friction. To understand kinetic friction, imagine you are in a rubber tube sliding across an infinite horizontal...

Static And Kinetic Friction Coulomb, a famous scientist in the eighteenth century was the first to mention static and kinetic (or sliding) friction, separately. Let a wooden block of weight W rest on a horizontal table. Weight W of the block acts on the table vertically downwards [Fig.]; ...
friction between the ground and its feet was too small. Kinetic friction, F K , This operates when two surfaces are sliding relative to each other. It is always directed opposite to the relative motion, tending to decrease the relative velocity. Static friction, F S , operates when ...
Objectives: Bodies in contact exert a force on each other. In the case of ideally smooth surfaces, this force acts perpendicularly to the contact plane. If the surfaces are rough, however, there may also be a tangential force component. Students will learn that this tangential component is a...

Static friction is greater than kinetic friction because there are more forces at work keeping an object stationary than there are forces working to resist an object once it is in motion.
These characteristics are not easy to quantify and vary from surface to surface. Hence even “good scientists”, or perhaps we should say “good engineers”, use the aforementioned fudge factors, the coefficients of static and of kinetic friction, in their calculations. ...
