Measuring the Experimental Period
7. Displace the car from equilibrium a specific distance and let it go. Time 5 oscillations
and record the time in Table 4.2.
8. Repeat this measurement at least 5 times, using the same initial displacement (ampli-
tude).
9. Add a 500 g mass to the car. Measure the time for 5 oscillations 5 times and record this
data in Table 4.2.
Calculations
Theoretical Period
1. Using the data in Table 4.1, plot force versus displacement. Draw the best-fit straight
line through the data points and determine the slope of the line. The slope is equal to
the effective spring constant,
k .
k = ______________
2. Using the mass of the car and the spring constant, calculate the period using the
theoretical formula. Also calculate the theoretical period for the car with the 500 g
mass in it.
