Physics Labs with Computers, Vol. 1Student WorkbookP26: Centripetal Force on a Pendulum 012-07000AAnalyzing the Data1. Click on the Graph Display to make it active. Rescale the Graph axes to fit the data.• In DataStudio, click on the ‘Scale to Fit’ button ( ).• In ScienceWorkshop, click on the ‘Autoscale’ button ( ).2. Find the maximum centripetal force and corresponding velocity value.In DataStudio, click the Force vs. Time plot to make it active. Click the ‘Smart Tool’ button( ).• Move the Smart Tool to the first trough in the plot of Force versus Time and read the valueof force. Record the absolute value in the Data Table in the Lab Report section.• Click on the plot of Velocity vs. Time and click on the Smart Tool button. A second SmartTool will appear. Place the tool at the velocity point that corresponds in time to the troughyou measured in the plot of centripetal force. Record the value of speed in the Data Table.In ScienceWorkshop, click the ‘Smart Cursor‘ ( ).• Move the Smart Cursor to the first trough in the plot of force versus time and read thevalue of force. Record the absolute value in the Data Table in the Lab Report section.• Press and hold the Shift key on the keyboard. The horizontal position of the Smart Cursorwill freeze. Move the Smart Cursor vertically into the plot of velocity and place the cursorat the velocity point that corresponds to the trough you measured in the plot of centripetalforce. Record the value of speed in the Data Table.3. Repeat the data analysis process for four more troughs on the plot of centripetal force.Record the maximum centripetal force and the corresponding speed in the Data Table inthe Lab Report section.4. For each value of speed you measured, calculate the centripetal force using the mass,speed, and length of the pendulum. Record the calculated value of centripetal force in theData Table.5. Calculate the percent difference between the measured centripetal force and the calculatedcentripetal force for each set of points. Record the percent differences in the Data Table.Record your results in the Lab Report section.p. 190 ©1999 PASCO scientific P26
Name _____________________ Class ______________ Date _________Lab Report - Activity P26: Centripetal Force on a PendulumWhat Do You Think?What are the factors that affect the centripetal force on a pendulum bob as the pendulum swingsback and forth? Does the centripetal force depend on how fast the pendulum bob is swinging?Data TablesItemValueDiameterMassLengthPoints Fc, measured (N) v (m/s) Fc, calculated (N) % difference12345Questions1. How do your measured values of centripetal force compare to the calculated values ofcentripetal force?2. What are possible reasons for the differences between the measured and calculated valuesof centripetal force?P26 ©1999 PASCO scientific p. 191
