This experiment flips that idea, finding the angular velocity based upon a known centripetal force. I had always thought of it as if the centripetal force necessary to keep an object moving in Uniform Circular Motion was dependent upon the angular velocity. This experiment was interesting in that it approached Uniform Circular Motion in a different way than I had ever experienced before. The whole setup process is somewhat confusing to convey in writing, but the end result was that the measured radius was always the same and the platform rotated uniformly.
We then set the radius of the Side Post assembly so that the rotating mass hung vertically when the indicator disk was aligned with its bracket. If it were not level, our results would be inaccurate due to a systematic error. PASCO Smart Timer Procedure To begin, we leveled the UCM Apparatus using a bubble level and various weights.Uniform Circular Motion (UCM) Apparatus, consisting of: o Variable-speed rotating platform o Side post assembly o Rotating Mass o Static Mass (varied) o Center post assembly with spring and indicator disk.These two values agree within their uncertainties. The end result of the lab was to compare the empirical and measured values of the rotating mass. We achieved this using a Uniform Circular Motion Apparatus and PASCO Photogates and Smart Timers, the employment of which is described below. Ben Stevenson Honor Code: _ Physics 116 Lab, Section 432 Investigation of Uniform Circular Motion Introduction In this lab, we examined the angular velocity of an object with varying centripetal forces.
