What is the distance from CBR to the equilibrium position?How far will you pull the pendulum away from the equilibrium position?_____________________________________________________ Calculate how long (in seconds) it took to complete one period. _____________________________ What is the benefit of timing ten complete periods instead of just one?Use the answer to question 2, and approximate the total distance traveled in one cycle. _________ Why is this value shorter than the actual distance traveled in one cycle?What do you notice about the shape of the plot?__________________________________________ How is the value from question 1 represented on the plot?__________________________________ Explorations 6. How does the appearance of the plot change?______________________________________ ____________________________________________________________________________________ 7. Using data collected from your plot, calculate the number of complete cycles per second. ________ Why is it easier to determine this using the second plot (spanning 5 seconds) rather than the first one (spanning 10 seconds)?_____________________________________________________________ 8. Calculate the frequency for one period using the equation. How does shortening the string length affect the period of the pendulum?_____________________ How does lengthening the string affect the period of the pendulum?__________________________ 10. What is the relationship between the amplitude of the pendulum swing and the total distance that the pendulum travels in one period?_____________________________________________________ ____________________________________________________________________________________ Advanced explorations 11. Compare the Distance-Time plot with the Velocity-Time plot. List similarities and differences. ______ ____________________________________________________________________________________ 12.
