UNBALANCED FORCES
PRELAB QUESTIONS
1) Describe the “Atwood’s Machine” used in this lab. What are some examples of similar types of mechanisms in everyday life?
2) How does the total mass suspended from the Atwood’s Machine change in successive runs in our experiment? Explain.
3) Why would it be much harder to predict the behavior of an Atwood’s Machine that used a heavy steel cable to connect the hanging masses instead of a very light string like ours uses?
4) What is a linear fit regression line and how is it calculated?
Explanation / Answer
(1) Atwood's machine is a lab equipment involving a pulley, string and a system of masses. The masses are suspended with the massless string over the pulley.
(3) The string has to be massless because otherwise, it would affect the result of the experiment.
(4) Linear regression consists of finding the best-fitting straight line through the points. The best-fitting line is called a regression line.
