What can you conclude from your experiments about the maximum static friction force between two surfaces ? Were your results reproducible? Why or why not? Once an object is in motion, it experiences kinetic friction. If a small amount of force is applied to an object, the static friction has an equal magnitude in the opposite direction. If the force is increased, at some point the value of the maximum static friction will be reached, and the object will move. The maximum force of static friction is μ s times the normal force on an object. In other words, F s ≤ μ s η , or F s max = μ s η, which means that maximum force of static friction is directly

proportional to the normal force. There is a great max amount for static friction with the plastic table top and paperback book than with the wood table and the hardcover book. Therefore the angle at which the book begins to slide is greater with a greater static friction because the downward force needed to overcome the frictional force increases as the angle increases and the results show this. The results were not reproducible because the surfaces may have inconsistencies and there was to much room for error when measuring the angle of the surfaces. Assignment is complete and correct, all or nearly all relevant physics principles appropriately applied, all or nearly all relevant steps described in complete sentences, all or nearly all necessary and relevant sketches clear and complete, few or no mechanical writing errors (19 points)

    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.
