PhysicsLAB Practice Problems
Frequency and Period #2

Topics: On this worksheet you will examine properties of a simple pendulum, vibration graphs, and graphs of Period2 vs Length.

Page Directions The numerical values in this worksheet are randomly generated allowing students the opportunity to conveniently practice, and drill, common situations.

Before beginning any given worksheet, please look over all of the questions and make sure that there are no duplicate answers shown for the same question. If duplicates are present simply refresh the page until every answer is unique.

In order to check an answer (even when you are just starting the worksheet on Question 1) it is necessary to omit any questions that you have not answered. Once you start submitting answers, the page may be checked as many times as necesasary without changing the randomized answers. Relevant scoring will be provided at the top of the page only when you answer all of the questions on your original submission.


Question 1  During an experiment, data is collected on the vibrations of a simple pendulum. A graph of Period2 vs Length is plotted and forms a linear graph with a slope of 3.76 and a y-axis intercept of 0.09. Use the fact that the numerical value of the slope represents 4π2/g to determine the value of gravity in the lab room.
Question 2  If the accepted value for gravity at sea level is 9.8 m/sec2, what was the percent error for this group's experiment?
Question 3  According to the data summarized by the group's regression line in Question #1, determine the frequency of a pendulum that was 105 cm long?
Question 4  How would the period of a 64 cm pendulum compare to the period of the pendulum in Question #3?
Question 5  What is meant by the term pendulum bob?
Question 6  What would be the correct units to measure the slope of the regression line described in Question #1?
Question 7  What is the frequency of a pendulum whose vibration graph is shown below if its 1st crest occured at t = 5.85 sec and its last crest occured at 52.85 seconds .


Question 8  Using the equation T = 2p SQRT(L/g) what would be the length of the pendulum in Question #7?
