This video touches on the basic physics and mathematics associated with simple pendulum motion. It includes basic mathematical relationships and demonstrations that are intended to provide high school physics students with insights into this most basic concept of 2-degree of freedom, oscillatory motion. The similarity between the motions of pendulums and flexible boom systems used on NASA sounding rocket plasma physics payloads is also made. This video is intended for high school teachers and students. More information on this topic and others can be found at labratscientific.com.
