Kevin Su Tues 8 to 10 Lab #5 Coefficient of Friction Introduction In this experiment we used a block with a mass resting flat on the surface. The two masses m1 and m2 are connected as pulleys to the block, by a thin, mass less string. I also measured the hanging masses, the mass of the block and the acceleration. So then we determined the coefficient of the kinetic friction. Procedures 1.) Measure the mass of the blocks and the mass hangers 2.) Make sure the strings are parallel to the surface of the dynamics tracks 3.) Start the computer and Logger Pro 4.) Open the file Probes and Sensors, and then open PHOTOGATES and select Pulley 5.) Lay the wooden block on its broadest side 6.) Then add the 50 grams to one of the hangers 7.) Then you can measure the measure the acceleration of the system by using the software 8.) Then after your done add another 25 grams to the hanging mass on the other side and then repeat procedure 7 and 9 9.) Then turn the friction block on its side. Then adjust the pulleys so that

### 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.
