Mass of car = ______________
Time for 2 oscillations
Springs Trial 1 2 3 4 5 Avg Period k
One
Series
Parallel
At Ends
Table 6.1
Calculations
1. Using the data in Table 6.1, calculate the average time for 2 oscillations.
2. Calculate the period by dividing these times by 2 and record the periods in Table 6.1.
3. Using the periods and the mass of the car, calculate the effective spring constants.
Questions
1. Is k
effective
=2k for springs in series or parallel?
2. Is k
effective
=1/2k for springs in series or parallel?
3. Is the last spring arrangement series or parallel?
