The purpose of this activity is to use the Stella model for a mass oscillating when attached to a horizontal spring to investigate the effect of the amplitude on the period of the oscillation.

Preliminary Questions:

1)     What effect do you think starting position will have on the period of oscillation?  In other words, if a mass on a horizontal spring is stretched greater and greater distances from its equilibrium position, will the period of oscillation increase, decrease, or stay the same?

3)     Describe a procedure that you could use to investigate question 1 using the Stella model built to represent a mass attached to a horizontal spring.

Investigation:

Carry out the procedure you described above investigating the effect of amplitude on the period of oscillation.  Collect and record results in a careful, organized manner.  Make sure to collect enough data to perform reliable mathematical analysis.

Analysis:

Graphically analyze your data in order to determine a mathematical interpretation of the data.  Record or print out your results.

Conclusion:

Write a summary of this investigation.  Be sure to describe your experimental procedure and to express what effect the amplitude has on the period.
