Centripetal Force Experiment
Purpose
The purpose of this experiment is to verify the accepted equation for the centripetal force of a mass during uniform circular motion. The hypothesis to be tested is that the calculated centripetal force for the stopper will be equal to the weight of the washers
Procedure
Begin this experiment by putting on safety goggles and collecting all of your materials; a tube, string, rubber stopper, tape, paper clip, washers, and a timer. Begin by measuring the mass of a washer, the rubber stopper, and a paper clip. Also measure the length of the string. Start with four washers on the mass hanger, as seen in the drawn diagram below. Practice swinging the stopper in a horizontal circular motion, holding it by the …show more content…

Such as the radius, which is the length of the string, at 0.45 meters. The mass of the stopper, which is the object experiencing centripetal force, at 0.0141 kilograms. The mass of one washer at 0.0056 kilograms. Lastly the mass of one paper clip at 0.0001 kilograms. The only dependent variable in this experiment was time. Due to the varying masses on the hanger the time for ten revolutions is what determines the experimental and theoretical centripetal forces. The longest time present in this experiment was 9.25 seconds for ten revolutions with four washers on the mass hanger. The shortest time present in this experiment was 5.15 seconds for ten revolutions with 20 washers on the mass …show more content…

Such as the experimental centripetal force, which is essentially the force of gravity found by multiplying the mass of the washers and paper clip by gravity (9.8 m/s^2). The highest experimental centripetal force was 1.107 Newtons, when there was the highest amount of mass on the hanger of 0.1130 kilograms. The lowest experimental centripetal force was 0.2293 Newtons, when there was the lowest amount of mass on the hanger of 0.0234 kilograms. The time period for one revolution was also found by dividing the time for ten revolutions by 10, the highest being 0.925 seconds when four washers were on the hanger and the lowest being 0.515 seconds when 20 washers were on the hanger. The velocity of the stopper was also calculated, the fastest velocity being 5.490 meters per second when there was 20 washers on the hanger and the slowest being 3.057 meters per second. Lastly the theoretical centripetal force was calculated, the highest being 0.9444 Newtons when 20 washers were on the hanger and the lowest being 0.2928 Newtons when four washers were on the
