Oliver, Douglas L. – Physics Teacher, 2018
The study of vibration in uniform beams provides physics teachers with a platform by which a broad range of physics vibration-related topics can be explored without expensive and specialized equipment. This paper presents two laboratory exercises related to lateral beam vibrations. These exercises use beam theory coupled with free sound-analysis…

Allen, Bradley; Liu, Tongtian – Physics Teacher, 2015
Calculating the effective resistance of an electrical network is a common problem in introductory physics courses. Such calculations are typically restricted to two-dimensional networks, though even such networks can become increasingly complex, leading to several studies on their properties. Furthermore, several authors have used advanced…

Oostra, Benjamin – Physics Teacher, 2014
I present a novel way to introduce the lunar orbital eccentricity in introductory astronomy courses. The Moon is perhaps the clearest illustration of the general orbital elements such as inclination, ascending node, eccentricity, perigee, and so on. Furthermore, I like the students to discover astronomical phenomena for themselves, by means of a…

Corrao, Christian T. – Physics Teacher, 2014
A challenge: Can you create a stable top from a single paper clip? Several interesting solutions to this problem were provided by Takao Sakai from Japan, the requirement of each being that the center of gravity be located on the vertical y-axis at the center of the top. In the simplest configuration, we see that there exists a single angle ?…

White, Susan C. – Physics Teacher, 2013
We have just completed the data collection for our 2012-13 Nationwide Survey of High School Physics and expect to have results to report in the spring. In the interim, we will take a look at physics in two-year colleges (TYCs). In 2007, we surveyed undergraduate seniors in degree-granting physics departments, and we asked these students if they…

Sabella, Mel S.; Van Duzor, Andrea G.; Passehl, Jennie; Weisenburger, Kara – Physics Teacher, 2012
Because of the diverse character of colleges and universities throughout the United States, it is naive to believe that a one-size-fits-all model of teacher preparation aligns with specific resources and student population needs. Exploring innovative models that challenge traditional programs is now being encouraged by organizations such as the…
