Oscillating+Particle+Lab+(Spring)

__Purpose -__ Determine relationship between the period of an oscillating spring and the change of amplitude, the change of mass and the spring constant.

__Data -__

Table 1 - change in length vs. force applied (Fg = mg)

Table 2 - change in amplitude vs. period

Table 3 - change in mass vs. period

Table 4 - change of spring vs. period

__Graphs -__

Graph- F vs. delta x - change in length vs. force applied (Fg = mg). Use the formula to find spring constant (slope of line). Graph- K vs. T - spring vs. period. Manipulate to make straight line. Rewrite formula for final graph.

Graph - Delta A vs. T - change in amplitude vs. period. (Make y-axis: min = 0 and max = 5)

Graph- m vs. T - mass vs. period. Manipulate to make straight line. Rewrite formula on final group.

__Calculations.__ Show one example of any calculations you made during the lab - average times, change in length, applied force, force constant)

__Questions__ 1. Compared to the the expected results (see Ch 13 - page 426-430). How where your results?

2. What is the difference between distorting force and restoring force on a spring?

3. What is the formula for a period of a mass on the spring? See WALKER book. How does this formula relate to what you see on the graphs from lab and the given graphs?

4. How would you do this lab using a horizontal spring? Does GRAVITY effect the results?
