Physics

Mr. Mirchel Regents Physics 6a/7 02 January 2012 Introduction Purpose: The purpose of this science laboratory was to sustain the relationship between sensory(a) force and centripetal speedup. The former(a) purpose of this lab was to experimentally determine the mass of an tutelage using the physics of circular motion. Hypothesis: I postulate the relationship between centripetal force and centripetal speedup to be direct. Experimental Design Equipment List: Plastic thermionic valve, string, steel washers, prophylactic plug, stopwatch, meter stick, triple beam balance, video show, metrical unit garments, safety goggles, and our brains! Diagrams of implement: Experimental Procedures: 1. We threaded the string by dint of the plastic subway system with a paper clip attached to one dismiss and a hawkshaw stopper attached to the other. Before proceeding, we overly made sure to co urse the apparatus and untangle the string. 2. We pulled the rubber stopper away from the pipework about .7 meters away from the tube and marked it by cohesive a piece of tape on the string infra the tube. 3. We measured the mass of 5 washers using a TBB. 4.

We put the 4 washers on the paper clip attached to the break off of the string, started swinging the rubber stopper, and change magnitude the speed until the tape mark was just below the tube all maculation making sure the tape didnt strike the bottom of the tube. 5. plot of ground maintaining the ideal speed, we measured the time requisite to complete 10 revolutions. 6. We repeated all procedures ! for different trope of washers in increments of 5. gumshoe Precautions: We were careful when swinging our apparatus, separated ourselves far from the other groups, and wore safety goggles at ALL TIMES. Observations/Results control attached. (Data Table) Data outline See attached. (Graph) See attached. (Calculations) What is the flush of the stoppers velocity? Explain.
