The coefficient of kinetic friction is typically denoted as μ k, and is usually less than the coefficient of static friction for the same materials   however, richard feynman comments that with dry metals it is very hard to show any difference. Lab # 5 - coefficient of static friction introduction it is a common observation that once set in motion objects invariably came to rest throw a book across a. I need lab report abt da coefficient of friction of wood & wood lik a complete report, if u did 1 before please send me one i have one due tomorrow, and was busy with other work.
Friction lab report purpose the purpose of this laboratory activity is to study how the coefficient of kinetic friction for an object depends on the mass of the. Kinetic friction or coefficient once static friction is overcome, kinetic friction follows and is the force holding back regular motion this kinetic cof concerns the force restricting the movement of an object that is sliding on a relatively smooth, hard surface. In this lab you will determine the coefficient of kinetic friction in two different ways and compare your results you will, in doing so, practice applying newton's 2 nd law to system and solving the resulting equations while getting a hands-on.
Friction, work, and the inclined plane objective: to measure the coefficient of static and kinetic friction between a block and an inclined plane and to examine the relationship between the plane's angle and its mechanical efficiency. 4) calculate the average static and kinetic coefficients of friction between the surfaces you selected 5) if a crate with a mass of 680kg were sitting on a level surface, and the crate and surface materials were the ones you used for lab, calculate the maximum static and kinetic horizontal frictional forces (use your average coefficients. In this experiment, you will determine the static friction coefficient of a block sitting on the lab vs normal force is the coefficient of kinetic friction.
Frictionlab friction lab home+ one of the formulas used on this lab is f fr = u k f n, calculate the coefficient of kinetic friction for the wood block. Lab instructor - mr smith static and kinetic kinetic friction occurs when two objects are moving against one another with conclude that the coefficient of. The coefficient of kinetic friction is the ratio f/w or mg/mg, or simply m/m based on the data you enter, if the ratio m/m is exactly equal to the selected μ, no motion will occur to cause motion, you need to slightly increase m , the hanging mass, by 01 gram, for example. Coefficients of friction lab summary and the kinetic frictional force versus the normal force to determine the coefficients of static friction and kinetic.
Measuring the coefﬁcient of kinetic friction introduction when two surfaces in contact move relative to one another in a direction tangent to. Both static and kinetic friction depend on the surfaces of the box and the floor, and on how hard the box and floor are pressed together we model kinetic friction with f kinetic = µ k n , where µ k is the coefficient of kinetic friction. Physics 31210 lab 3 static and kinetic friction introduction: friction can thought of as a force that opposes motion it never pushes (the coefficient of kinetic. Both static and kinetic friction depend on the surfaces of the box and the floor, and on how hard the box and floor are pressed together we model kinetic friction with f kinetic = μ k n , where μ k is the coefficient of kinetic friction. Physics laboratory report friction coefficient of kinetic friction with other lab groups to expand the number of sole-flooring combinations.
Projectile motion lab by tom blum pyl 105 enter the value you find for the coefficient of kinetic friction in the table. Coefficient of kinetic friction only depends on the nature of the surfaces it does not depend on any other factors, including the relative speed of the. Physics 100 friction lab coefficient of kinetic friction = _____ pg 5 5 predicting and testing the frictional force for a different system now that you have the. Kinetic friction coefficients are generally less than static friction coefficients, which is the reason that it is much easier to keep a heavy object in motion than it is to start it in motion  the.
Experiment 5 ~ friction purpose: in this lab, you will make some basic measurements of friction first you will measure the coefficients of static friction between several combinations of surfaces using a heavy block and. Lab coefficient of friction in this section of the experiment you will use your knowledge of obtaining the coefficient of kinetic friction on an incline plane to.
