Post-lab Week 6

UCLA Physics Department

1

Post-Lab Requirements for lab 3C

• Plot your distance vs. time for the damped oscillator. Be sure to include a title, axis labels, the best-fit, and a legend

​

• Plot your energies vs. time (kinetic, potential, and total). Be sure to include a title, axis labels, the best-fit, and a legend

​

• Describe the shape of your total energy over time. Explain whether this result makes sense based on the model for the damped harmonic oscillator

Post-Lab Requirements for lab 3D

• Plot your ultrasonic sensor distance vs. time at or near to the resonant frequency of your system. State the resonant angular frequency of your system, calculated from forceHalfPeriod
• Create a scatter plot of settling amplitude vs. the ratio between the driving frequency and the natural frequency of the system. This should include >= 5 data points (>= 2 below resonance, >= 2 above resonance, 1 at resonance). Use both plt.scatter and plt.plot to generate this plot

​

• You must submit one document for your group on Gradescope

Make a copy of this document to submit the post-lab for Week 6.
