Lab: Spring-Mass Oscillation
Purpose:
Find the relationship , between the period and the mass with the same spring and between the period and the spring constant with a constant mass.
Equipment:
Spring. various mass, motion sensor, ruler
Experiment:
1. Set up the apparatus as the pictures show.
2. Hang a 50g mass on the spring and measure the length of the spring L1; Hang a 100g mass on the spring and measure the length of the spring L2
3. Calculate the spring constant based on the mass and the difference of length.
4. Calculate the mass needed to reach the same total mass with other group.
5. Hang the calculated mass on the spring and stretch a little so that the mass oscillates, and record the period.
6. Write down the data from other group, and create a graph of spring constant vs. period with the same mass.
7. Hang different mass on the same spring and record the period for each oscillation.
8. Create a graph of mass vs. period.
Result:
Conclusion:
Graph of Period vs. Mass: y=2.686*x^0.4632
Graph of Period vs. Spring constant: y=2.570*x^-0.5702
