(car with mass) T = ________________
Experimental Period
1. Using the data in Table 4.2, calculate the average time for 5 oscillations with and without
the 500 g mass in the car.
2. Calculate the period by dividing these times by 5. Record the periods in Table 4.2.
Comparison
Calculate the percent difference between the measured and theoretical values:
(car alone) % difference = ________________
(car with mass) % difference = ________________
Questions
1. Does the period of oscillation increase or decrease as the mass is increased? Does a more
massive car oscillate faster or slower?
2. If the initial displacement from equilibrium (amplitude) is changed, does the period of
oscillation change? Try it.
