value of the coefficient of kinetic friction. We examined whether or not the angle of incline plane affects the coefficient. We used different angles in part 1 to 3 and experienced that the coefficient of kinetic friction was getting larger as the angle was getting wider. The value of sliding friction does depend on the normal force between the object and the surface. This is shown by the equation, f k = μ k N . Whenever the normal force increased, the frictional force increased. The value of sliding friction between two objects does depend on the surface and the material are in cantact with it. I would use rubber when pulling the wood with the newton meter to reduce the error in measuring μ . I believe by using a metrial of higher μ , any small changes in value of the coeffiecient of friction will be hard to detect as the actual value is so much larger. In general, whenever the measured value is much greater than the uncertainty, error is decreased. Reference: Works Cited College, O. (2015, Jan 23). College physics 5.1 Friction .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
