Bryan (Daejin) Kim 2/14/07 1 PHY131L – DYNAMICS OF UNIFORM CIRCULAR MOTION Objective To be able to calculate the centripetal acceleration of a spinning apparatus Equipments - uniform circular motion apparatus - 1-kg weights - Dial caliper - Stopwatch - Slotted weight set - Weight hanger Procedure At first, we prepared the uniform circular motion apparatus. By tilting this sideways, we were able to weigh weights on it to measure the force required to stretch the spring to the end of the apparatus. We put weights on it until the body of mass barely touched the rocker, so that the rocker pointed exactly in the middle of the index (axis of rotation). Then, we took off the weights and tilted the apparatus back to vertical. By turning on the engine, the apparatus started to spin. As we increased the rpm, the body of mass began to stretch the spring and extend outward the circular motion. We found the exact point where the body touched the rocker the same way it did when we were weighing on it. At this point, my partner started the stop watch, and at the same moment he pressed reset to measure the total revolution. As he stopped the stopwatch around one minute, we froze the apparatus screen to find out exactly how many revolutions it has made. We started over and re-did this three

### 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.
