# Spring Constant Plot Elastic Force and Periodic Motion Pre Lab Questions

Anonymous

### Question Description

What is the purpose of making the weight vs. spring constant plot? What do we want to get from that plot?

2. Why do we measure the elapsed time for 20 oscillations instead of just one?

3. If we plot m vs. T2 for the simple harmonic oscillator, what do we expect the graph to look like?

4. After making this plot the manual asks you how your result compares with theory. How should you check this?

5. Explain how it is possible to use the simple harmonic oscillator to measure the unknown mass.

1. What is the purpose of making the weight vs. spring constant plot? What do we want
to get from that plot?
The purpose of making the weight versus of spring constant plot is to enable us to get the
displacement.
2. Why do we measure the elapsed time for 20 oscillations instead of just one?
We measure 20 oscillators instead of just one to reduce the uncertainty in the
measurement by measuring oscillations and calculating...
