October 24, 2015 CENTRIPETAL FORCE AND ACCELERATION Abstract We performed an experiment to determine the centripetal force and period of revolution and prove if the same centripetal force and radius are kept constant, then the new mass and frequency can be expressed by Equation 4. The mass of the bob and radius was measured and the spring force was calculated. The time for 50 revolutions was measured and the time of one revolution, centripetal force, frequency of rotation, and theoretical frequency was calculated. The percent difference between spring force and centripetal force was calculated. The f 2 and W were exported onto Excel and the equation of a line was generated, y = 0.2883 x + 0.0169 . The slope we acquired was 0.2883, but when using Equation 5 to determine the slope it was 0.2378. In order to prove Equation 4, a new mass and time for 50 revolutions was measured and new spring force, time of one revolution, centripetal force, frequency and theoretical frequency was calculated. The calculated f ‘ from Equation 4 was 1.2262 Hz and the average f was 1.994 Hz. Theory, Materials, and Methods The apparatus used in this experiment is shown in Figure 1. The mass of the bob was recorded and the radius from the center of the bob to the center of the shaft was measured. A string was attached to the bob and over the pulley on the other end of the string weights from 0.700 kg to 0.300 kg, in 0.100 kg increments was attached. The spring force was calculated with Equation 3.

In order to determine the period of revolutions and centripetal force, the apparatus was used again. A string was attached to the bob and over the pulley on the other end of the string weights from 0.700 kg to 0.300 kg, in 0.100 kg increments was attached. The indicator was placed under the bob for each weight. The weight and string were removed. The top part of the shaft rotates the apparatus. The bob must hit the indicator and the time was measured in seconds for 50 rotations. The

### 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.
