Over the course of this video project,
we set out to analyze the real life application of two physics topics we have
learned throughout the year in class. We analyzed both simple harmonic motion
as well as projectile motion, with the projectile being Cam’s body. As Cam was
on the swing, he was subject to simple harmonic motion, with the swing acting
as a simple pendulum. From this motion, we withdrew several different aspects
of the pendulum, including period, frequency, angular frequency, and amplitude.
After completing half of a period of the pendulum’s motion, Cam then exited the
swing and underwent projectile motion. From this motion, we withdrew even more
information, including: x and y position, velocity, acceleration, and different
forms of energy. We found through the course of this project that the
techniques we learned in class still apply to real-world situations, yet with
some error involved. It was particularly interesting to notice how all of the
different information coincided with each other. For example, when potential
energy was at a minimum in Cam’s motion, his kinetic energy was then at a
maximum. Although this video analysis was not done in an ideal “physics” world,
the data obtained from the video was still quite valid. Furthermore, the analysis
we ended up obtaining from this data allowed us to analyze not just one form of
motion- we were able to demonstrate both SHM and projectile motion.
