Measurement of Coefficients of Friction

1)Objective and Motivation

◎Measure the static coefficient of friction and kinetic coefficient of friction in various methode and mass, then compare each others.
◎Find the cause of the errors and discuss how they effected on data.

2)Theoretical Background and method

(1)Friction

The definition of friction is `The force resisting the relative motion of solid surfaces, fluid layers, and/or material elements sliding against each other. It may be thought of as the opposite of `slipperiness`.`(Wikipedia `friction`). The friction is caused by electric force between surfaces of materials.
The friction force is determines by normal force()and coefficient of friction(). And the equation of frictional force is .

(2)Coefficient of Friction

The definition of coefficient of friction is `dimensionless scalar value which describes the ratio of the force of friction between two bodies an…(생략)
