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 and the force pressing them together`(Wikipedia `friction`). This valu…
