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 value is depends on the materials used.
The static friction is `friction between two solid objects that are not moving relative to each other.` There is a maximum friction or limiting friction in static friction. After limiting friction, friction change to kinetic friction. Kinetic friction is smaller than limiting static friction. Also coefficient of static friction is bigger than coefficient of kinetic friction. The friction is caused by cold-welding of atom at surface. To move, the force should big enough to break this welding and this is the origin of kinetic friction. But in real case there are oxides so cold-welding effect decrease. But after moving cold welding are form in very short time so kinetic friction is smaller than limiting friction.

First, with out pulley we can change the angle and che
