GRAPHS Attach Pasco graph of angular speed for the 15-cm radius, 20-g mass configuration. Attach Pasco graphs of hanging mass versus mean angular speed and radius versus mean angular speed . SAMPLE CALCULATIONS For the 20 gram mass, attached when the side post was at a distance of 15.0 cm from the center post, show the calculation for the uncertainty for the mean angular speed σ ω = ¿ Experimental mass m calculated from the trendline of the graph of hanging mass versus angular speed: m = ¿ Experimental mass uncertainty calculated from the graph’s trendline of hanging mass versus angular speed: δm = ¿ Experimental mass m calculated from the trendline of the graph of radius versus inverse angular speed: m = ¿ Experimental mass uncertainty calculated from the trendline of the graph of radius versus inverse angular speed: δm = ¿ Percent Difference between the two experimental masses: PD = ¿ Lab 5: Centripetal Force 3 of 5
