This video could be used as part of a lab experiment on oscillations for an introductory physics class.
Please note that after 5:07 or so, the text in the video suggests that you should find "g" from the trendline. This is a typo, and it should say to find "k", the spring constant, from the trendline.
A set of masses is hung from a spring.
The thin mass is 50.0 g, the middle mass is 100.0 g and the thick mass is 200.0g. The hanger itself has a mass of 17.0 g.
Students use the combination of these masses to determine the total.
Students find the start and end time for 20 oscillations.
This can be done by pausing the video using the space bar. Clicking the "," or "." keys allow one to step frame by frame (Note the , key has the greater than symbol above it and . has the less than symbol above it to help you remember this.)
The difference in the start and stop times is divided by 20 to give the period of oscillations. T = (tf - ti)
The frequency is then determined by f = 1/T
A plot of frequency vs. mass can be analyzed several different ways.
A plot of frequency^2 vs. mass can also be analyzed.
There is no sound for this video.
