Science Homework Help. Simple Harmonic Motion Experiment
Run the simulation and get the data!!! (Links to an external site.)
Video: Simple Harmonic Lab Lecture (Links to an external site.) As mentioned in the video – I had an issue with my stop watch! It was doubling the time. It has been fixed.
There are 2 parts to the lab, spring oscillation and pendulum oscillation. The g used for the experiment is 9.81 m/s2.
For the pendulum, ordinarily we would have you put different objects at the end of the pendulum and measure their mass. I wrote code that allows you to choose the mass of the object. I think I need to rewrite the code and make the relation between mass and radius non-linear, maybe I will before you see the lab. Anyhow, for 4 different masses, measure the time for 20 oscillations, keeping the length constant – maybe try 80 cm at 2 degrees max.
Then continuing with the pendulum, for a fixed mass, measure the time for 20 oscillations for lengths 20, 40, 60, and 80 cm.
For the spring, record the location of the end of the spring for having 0, 100, 200, 300, 400, and 500 g attached to it (technically 0 g is nothing attached). Then measure the time for 20 oscillations for 100, 200, 300, 400, and 500 g attached. Don’t forget to record the mass of the spring!
Then lots of calculations await…a you will need 3 graphs with best-fit lines included with your report – T2 vs L for the pendulum, F vs d and T2 vs (mattached+1/3 mspring) for the spring.
