Burris, Jennifer L.; Hester, Brooke C.; Mamola, Karl C. – Physics Teacher, 2018
It is common in introductory physics to show that in the absence of air drag an object dropped from rest will reach the level ground at exactly the same time as one that is projected horizontally from the same height. However, the situation is different in the presence of a speed-dependent drag force, as either object may hit first or they may hit…

Jumper, William; Dy, Simthyrearch – Physics Teacher, 2018
The debate over the mechanisms responsible for the flow rates of simple tube siphons has received much attention in the physics education and general physics literature in the past decade. Particularly with regard to the driving mechanism for water siphons, some suggested explanations emphasize contributions, or lack thereof, from the atmospheric…

Little, Angela; Elliott, Leslie Atkins – Physics Teacher, 2018
In this paper we describe an activity for engaging students in crafting definitions. We explore the strengths of this particular activity as well as the broader implications of engaging students in crafting definitions more generally.

Vera, Francisco; Fernandez, Nicolas; Ortiz, Manuel – Physics Teacher, 2018
In this paper we describe a simple alternative to the telephone book friction experiment, a classic demonstration where a small force (generated for example by the bending of the outer pages) is amplified by the large number of surfaces in contact, resulting in a huge maximum static friction force that has to be counterbalanced in order to…

Frank, Brian W. – Physics Teacher, 2018
The goal of this paper is to illustrate different ways that cardsorting activities (or "card stacks") can be implemented in the introductory physics classroom, along with various tips and resources for getting started. My first attempt at developing a card stack came about from simply wanting to try out a fun way to change student…

Bensky, William C. – Physics Teacher, 2018
Although mainly used by the hobby or "maker" crowd, the Arduino microcontroller has made its way into all levels of education, including physics labs. Perhaps the most compelling aspect of the Arduino in this regard is the ease with which it can be interfaced and acquire data from a sensor, using any one of its many analog inputs, SPI or…

Teng, Bettina; Teng, Peter; Hennekens, Charles H. – Physics Teacher, 2018
Young's experiment is hailed as a milestone in ushering a new understanding of the wave nature of light and is even taught at the high school level. Unfortunately, even the most cursory presentation of the subject of diffraction becomes confusing. The theory and equations based on Fresnel's work appear arcane and incomprehensible to a high school…

Lynch, John J. – Physics Teacher, 2018
This work describes a way to study uniform circular motion (UCM) using a LEGO® MINDSTORMS® Robotics Invention System (RIS) stepper motor with a steel ball attached to a string. The equipment is inexpensive and the resulting motion takes place on a human scale. Times and lengths can be measured with a stopwatch and a meterstick, respectively. In…

Goh, Ker Liang – Physics Teacher, 2018
If a body is in equilibrium under the action of three non-parallel coplanar forces, the forces must be concurrent, that is, must meet at a single point. Specific examples are provided here to illustrate the validity of this statement by the use of free-body diagrams as well as during the discussion of equilibrium and moments. These cases are…

Cross, Rod – Physics Teacher, 2018
The acceleration of a vehicle or a bicycle is commonly used in elementary physics courses to illustrate problems concerning Newton's laws of motion when friction forces are involved. The maximum possible acceleration is rarely discussed, although it is of interest to consumers and racing car enthusiasts, and it is sometimes questioned by students.…

Rojas, Roberto; Robles, Patricio – Physics Teacher, 2018
Two bodies initially at different temperatures gathered into an isolated container exchange heat and reach an equilibrium state with a common final temperature. During the process, the system is out of equilibrium and its intermediate temperature is not well defined. By conceiving a quasi-static process with infinitesimal steps from the initial to…

Gunderson, Ross – Physics Teacher, 2018
With any piece of technology, there exists a learning curve where students need time to adjust to the ways in which the device works. If you struggle with having enough time for lab, it may be advantageous to have students learn how to operate one set of equipment and use that equipment as much as possible. In this article a unique application for…

Laumann, Daniel – Physics Teacher, 2018
In our everyday life, it seems that magnetic phenomena are restricted to ferromagnetic materials or electromagnetism caused by electric currents. From a physics point of view, we know that this everyday experience is contrary to the nature of magnetic phenomena. If one regards the magnetic properties of the elements of the periodic table in their…

Lincoln, Don; Olson, Lindsay – Physics Teacher, 2018
One author of this article is a particle physics researcher; the other is an artist. Although they come from different sides of the spectrum of liberal arts, what they share in common is that they are both communicators and educators. This article tells the story of how this unlikely pair came together to collaborate and generate creative art that…

McPadden, Daryl; Dowd, Jason; Brewe, Eric – Physics Teacher, 2018
Power Boxes are a new representation to provide students with a conceptual resource to analyze direct current (DC) circuits and to build conceptual understanding of energy and power use in circuits. Power Boxes are designed to provide an intermediate, conceptual step between drawing a circuit diagram and solving calculations. In this paper, we…
