Physics 111 Lab 9: Uniform Circular Motion Names of the students who worked on this lab (each student should use a different color): Emmie Nguyen, Veronica Hernandez , Mohammed Alhumidiaherz, Tanner Myhre When you are done with the lab, please fill out the peer evaluation form linked below for you and your partners. If you don’t fill out a peer evaluation and defend any low scores by the day after the lab is due, you will lose 2 points. Xrv3_Op0zguqw7A/viewform?usp=sf_link Materials : String Stopwatch or anything to keep time. Most cellphones have this feature. Three objects with different mass. You have to be able to tie a string around them and safely swing them without breaking anything. Scale Tape measure or ruler Enough room to safely swing an object over your head without hitting anything. Part 1: Varying Masses 1. Measure all three masses on a scale, in kilograms. A standard bathroom scale may not have the precision to weigh the smaller objects, so you’ll probably have to use a kitchen scale. Be sure to convert the mass in grams or pounds to kilograms! Look up the conversion factor between kg and lb if necessary. Record the three objects and their masses on the table below. 2. Measure off 0.5 m of string and tie one end to the medium-mass object. If you only have a yardstick or a ruler that doesn’t measure in cm, you can do a Metric conversion. 3. Tie the medium-mass object to one end of the string. Swing it above your head in a circular motion. Try not to move your hand too much. Measuring time with the stopwatch, how many full revolutions can you make the object do in 10 seconds?

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."
— Christopher R., University of Rhode Island '15, Course Hero Intern

### 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.
