Sliding friction

How to measure friction? Method 1 Weight ratio The sketch shown originates from Leonardo da Vinci ca He studied friction by measuring the load hanging on a cord, at which the block begins to slide.

Sliding friction


Sliding friction Friction Equation by Ron Kurtus revised 21 October The standard friction equation shows the relationship between the resistive force of friction, the coefficient of friction and the normal force pushing the objects together.

The equation applies in most friction situations. Questions you may have include: What is the standard friction equation? What is the coefficient of friction? What is the normal force?

This lesson will answer those questions. Units Conversion Standard friction equation The standard equation for determining the resistive force of friction when trying to move two objects or materials with respect to each other shows the relationship between the force of friction, the coefficient friction, and the normal force pushing the two objects together.

Coefficient of friction The coefficient of friction COF is a number that determines the amount of friction between materials in contact. In most cases, the COF is also independent of the area of the surfaces in contact.

Factors determining the COF include combinations of materials, surface conditions, and whether the motion is in the static mode or kinetic mode. The COF is also different for the various types of friction: For more information see:Sliding friction refers to the resistance created by any two objects when sliding against each other.

This friction is also known as kinetic friction and is defined as the force that is needed to keep a surface sliding along another surface. Super-low-friction stick-on dance soles for easy pivoting and sliding on concrete, asphalt, carpet, and very sticky indoor dance floors.

With 3M LSE industrial-strength, self-adhesive backing. The coefficient of friction between two materials in relative sliding may depend on contact pressure, surface roughness of the relative harder contact surface, temperature, sliding velocity and the type of lubricant whether the level of contamination.

Coefficient of friction

A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.
