Kianian, Kiarash; Bozorgmehr, Aria – European Journal of Physics Education, 2017
In this paper, we indicate the difference between energy equation and the center of mass equation by an especially example. According to our opinion, in teaching mechanics, we should more clearly an integral of Newton's second law and the energy equation. Maybe this leads to greater clarity in the notions of system, work and energy.

Montecinos, Alicia M. – European Journal of Physics Education, 2014
A partially unusual behaviour was found among 14 sophomore students of civil engineering who took a pre test for a free fall laboratory session, in the context of a general mechanics course. An analysis contemplating mathematics models and physics models consistency was made. In all cases, the students presented evidence favoring a correct free…

Forjan, Matej; Sliško, Josip – European Journal of Physics Education, 2014
This article presents the results of an analysis of three Slovenian textbooks for high school physics, from the point of view of simplifications and idealizations in the field of mechanics. In modeling of physical systems, making simplifications and idealizations is important, since one ignores minor effects and focuses on the most important…

Bertel, Erminald – European Journal of Physics Education, 2013
Due to progress in nanotechnology high-quality quantum wires can nowadays be fabricated. The behavior of particles in one dimension differs significantly from that in three-dimensional (3D) systems, yet the physics of such low-dimensional systems is generally not very well represented in standard undergraduate or graduate curricula. For instance,…

Kuhn, Jochen; Vogt, Patrik – European Journal of Physics Education, 2013
New media technology becomes more and more important for our daily life as well as for teaching physics. Within the scope of our N.E.T. research project we develop experiments using New Media Experimental Tools (N.E.T.) in physics education and study their influence on students learning abilities. We want to present the possibilities e.g. of…

Podolak, Ken; Danforth, Jordyn – European Journal of Physics Education, 2013
There are a variety of teaching tools available for use in introductory modern physics classrooms. Determining which teaching tool students support can help the teacher structure classroom instruction to include more effective teaching tools. Student participants were surveyed at the end of four separate semesters after using different teaching…

Sznitman, Josué; Stone, Howard A.; Smits, Alexander J.; Grotberg, James B. – European Journal of Physics Education, 2013
Dimensional analysis is often a subject reserved for students of fluid mechanics. However, the principles of scaling and dimensional analysis are applicable to various physical problems, many of which can be introduced early on in a university physics curriculum. Here, we revisit one of the best-known examples from a first course in classic…

Syam, Debapriyo; Roy, Arup – European Journal of Physics Education, 2011
The Bohr-Sommerfeld quantum theory specifies the rules of quantization for circular and elliptical orbits for a one-electron hydrogen atom-like system. This article illustrates how a formula connecting the principal quantum number "n" and the length of the major axis of an elliptical orbit may be arrived at starting from the quantum…
