Article
The Sun does not return to the same position in the sky every 24 hours. At local noon, for example, the Sun will appear higher in the sky as we move from winter to summer solstice. In addition, and perhaps more surprisingly, solar days (the roug[...]

In the museum wing of the Greenslade house is a clock with a two-second pendulum about one meter long (Fig. 1). This ticks once per second, and every time it passes through dead center it completes an electrical circuit. When I came to Kenyon in[...]
Article
In this note, the classical Doppler shift for some accelerated mechanical systems is considered under a common graphical approach. In one dimension, we study uniform accelerated motion and simple harmonic motion. In two dimensions, uniform circu[...]
Article
The stately fall of magnets through conducting pipes is a favorite classroom and laboratory activity used in teaching electromagnetic induction, Lenz’s law, eddy currents, electromagnetic braking, and even Newton’s third law.
Article
Races between moving objects are an engaging way to teach dynamics to introductory physics students. One standard example consists in racing hollow and solid cylinders as they roll down an inclined plane. Another striking demonstration is a race[...]
Article
In our first-semester introductory physics laboratory, we have an exercise on rotational dynamics. We have recently upgraded the equipment that we use in that exercise without changing the actual exercise. The new equipment has performed well so[...]
Article
Electromagnetism (E&M) is often challenging for students enrolled in introductory college-level physics courses. Compared to mechanics, the mathematics of E&M is more sophisticated and the representations are more abstract. Furthermore, students[...]
Article
Bell’s theorem is a topic of perennial fascination. Publishers and the general public have a steady appetite for approachable books about its implications. The scholarly literature includes many analogies to Bell’s theorem and simple derivations[...]
Article
While AAPT and many other physics organizations have been introducing a series of effective practices around diversity and inclusion at the national level in recent years, it was wondered if these were being adopted at the local level. It is hop[...]
Article
The standing vertical jump (SVJ) is a classical topic in Newtonian mechanics (Fig. 1). Although the topic has also been treated by others (other terms used are “standing high jump” or “squat jump”), the present paper shows how a smartphone can b[...]
Article
Implementing smartphones with their internal sensors into physics experiments represents a modern, attractive, and authentic approach to improve students’ conceptual understanding of physics. In such experiments, smartphones often serve as objec[...]
Article
The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific’s Smart Cart, in combination with student-owned smartphones and free apps, has opened a new universe of low-cost experiments that have trad[...]
Article
There is no shortage of great pedagogical tools available, but many require considerable investment of time and effort (and oftentimes money and equipment), which can be a significant barrier for already time-poor teachers. Wonder Questions is a[...]
Article
Physlets, educational applets developed at Davidson College, are a widely used teaching resource designed to simulate a variety of physical phenomena. Originally, each Physlet was a Java simulation that was embedded in an HTML page as an applet [...]
Article
Shadows produced by sunlight reflected from convex surfaces can be very well defined. This article provides an explanation for this phenomenon as well as a demonstration/lab activity for students to investigate properties of shadows made from su[...]
Article
Einstein’s special theory of relativity includes many non-intuitive and apparently paradoxical conclusions about space and time. One of these is time dilation, the fact that a clock moving relative to an observer runs slower than an identical cl[...]
Article
In a typical first physics class, homework consists of problems in which numerical values for physical quantities are given and the desired answer is a number with appropriate units. In contrast, most calculations in upper-division undergraduate[...]
Article
Physics teachers around the world are trying to create classroom environments that would allow life science students to be more intrinsically motivated in their work. These efforts include, among others, matching classroom activities to students[...]
Article
The falling temperature of the photosphere with height is responsible for the effect known as limb darkening. The Sun is not equally bright all over the disc. When we observe the Sun towards the limbs, it appears to get darker. Light from the ph[...]
Article
About 30 years ago I taught a series of summer enrichment programs for high school physics teachers, using funding from the Howard Hughes Medical Institutes. I deliberately chose teachers from smaller cities and towns who were unlikely to have c[...]
Article
Nowadays, electronic devices (especially smartphones) are developed to use as an alternative tool for recording experimental data in physics experiments. This is because of the embedded sensors in a smartphone such as the accelerometer, gyroscop[...]
Article
X-rays are such an important and familiar part of the electromagnetic spectrum, but is there a way to safely bring x-rays into your lecture? The demo team at the University of California at Berkeley seems to have managed this. They have an x-ray[...]
