Simulated Spring Lab

Experiment with the lab below to answer some questions concerning springs.


1) Figure out a way to determine the spring constant k of Spring 1, and explain your reasoning.
Hints: Recall that the spring constant k is defined by Hooke's Law |Fspring| = k x , where x is the amount of stretch of the spring. Also, You can "zoom in" by right-clicking with the mouse The ruler can be moved by left-clicking and drag.

2) Make a graph of stretch x vs. mass hung. (Use the graph paper on next page). How could the spring constant k be determined this graph?

3) Using your results from part 1, determine the masses of the three colored unknown masses. Explain what reasoning you used to find the mass.

4) Determine the acceleration due to gravity on Planet X. Explain how you found the value.
