Lab: Springs Round II - Santa Monica High School Physics
Lab: Springs Round II
1. Determine the k-value of your spring. Show work below.
2. Displace your mass 3 cm from its equilibrium position and release it from rest. Measure the time it takes the mass to complete five oscillations. What is the period of your mass-spring system (time for one oscillation)?
3. Repeat step 2, except this time displace your mass 5 cm from its equilibrium position.
4. As amplitude increases, what happens to the period of a mass-spring system?
5. Calculate the angular frequency of the mass-spring system using the values of m and k (determined in #1). Use this to calculate the frequency and period of the mass-spring system.
( = f = T =
6. Compare your calculated value of the period to the experimental value you obtained in step 2. Determine the percent difference.
7. Now attach a second spring to your mass and displace the spring from its equilibrium position and release it. Record the period below.
8. Remove the second spring and attach it to the end of the first spring to make one long spring. Displace the spring from its equilibrium position and release it. Record the period below.
9. What do you think the effective k value of your mass-spring system was in step 7 (in terms of the original k you found in #1)?
10. What do you think the effective k value of your mass-spring system was in step 8?
