Victoria WoodPartner: ShamsaPHYS 221: Section 1Experiment 6: Coefficient of Friction
ResultsIn this lab, we obtained data from various methods - force probe, block on incline,constant velocity and angle of repose – to understand how to obtain the coefficientof friction and calculate force needed to pull an object up at a constant speed. Withvarying masses, the coefficient of friction usually increased, due to more weightbeing put on moving block. Some of the coefficients of friction did not increase andsometimes even lowered, which could be due to human error and the fact that wepulled the block either too quickly or too slowly and did not obtain reliable data tobase our equations on. Each method worked differently, some required angles andconstant movement tests, while others required horizontal planes. I think that everytest worked quite well to come up with the coefficient of friction and force needed tomove the block though. I learned that there are many ways to test for the same
