Pre Lab
This week's lab will explore oscillations and simple harmonic motion. This is a topic we have touched on at different points during the semester. Simple harmonic motion describes motion that repeats itself in amplitude (how far) and frequency (how often). As we have learned before, if no external work is done, then energy is conserved. This is true for simple harmonic motion as well.
Specifically, in this lab we will look at how energy is conserved as a mass hanging on a spring oscillates up and down. The total mechanical energy in this case is the sum of the kinetic energy, gravitational potential energy, and the elastic potential energy. Total Mechanical Energy = KE + PEG + PEE
Total Mechanical Energy = ½ mv^2 + mgh = ½ k y^2 This lab will involve a theoretical/calculation section and then a video analysis of position, velocity, acceleration, and energy of the oscillating mass.
Prior to lab please complete the following:

Videos about Simple Harmonic Motion.
A long lecture on the topic. You don't have to watch the whole thing, but he does do some fun demos.
