Have you ever hurt your knee when sliding on carpet? Discussion Assumptions 1. Collect three of your school textbooks that are different size and weight (you can use books of various sizes that you have at home as well). Notice that there is a different coefficient for static and kinetic (sliding) friction. This in turn makes the football slow to a stop and enables the football to be caught. Answers to Worksheet Questions Q. Let me look at one more case, and then I will offer things that could be explored. Make an easy magnet maze with cardboard or even a LEGO maze. In football we often want to maintain contact with a surface to utilize good friction to our advantage, but at the same time, we might not want materials heating up or slipping, so players desire to minimize poor friction. Being sure not to damage the textbook, slide the textbook along various surfaces, keeping a keen eye on the frictional force that each surface has on the movement of the textbooks. I thought that the Then, by using formula of coefficient of friction we found the value, which was approximately 0.18 at 10, 20 and 30. We put 1,000 grams on top of the brick for each trial. Coefficient of Friction 2022-10-27. The measuring process is developed by means of moving plane made of the material we want to study and knew longitude, which can regulate its angle by growing or reducing its height. Q. Since friction is a force, the unit of the frictional force is the newton N. Also, we can ensure the applied force is horizontal by fixing the spring balance on a horizontal platform. Find out why you slip and slide more on smooth surfaces than rougher surfaces with this slipping and sliding activity. 31 1 CONCLUSION It is generally recognized that control of friction processes is extremely diffcult, or even impossiblebecause of the complexity and diversity of phenomena occurring on a standard dynamic contact.
