Sengul, Ozden – European Journal of Physics Education, 2019

This study explored how research-based physics tutorials help students use argumentation in a small group-work activity. The participants were four first-year non-major physics students taking algebra-based introductory physics course in an urban university in the southeastern region of United States (US). The content analysis was conducted to…

Dean, Kevin – European Journal of Physics Education, 2018

The conical pendulum provides a rich source of theoretical and computational analysis and the present work presents a seamless continuation of the previous publication. The tension force F[subscript T] and centripetal force F[subscript C] are explored further in linearization analyses and the appropriate slopes are explained. A similar analysis is…

Arlego, Marcelo; Fanaro, Maria de los Angeles – European Journal of Physics Education, 2017

In this work, we present a pedagogical strategy to describe the diffraction phenomenon based on a didactic adaptation of the Feynman's path integrals method, which uses only high school mathematics. The advantage of our approach is that it allows to describe the diffraction in a fully quantum context, where superposition and probabilistic aspects…

Dean, Kevin – European Journal of Physics Education, 2017

This paper represents a continuation of the theoretical and computational work from an earlier publication, with the present calculations using exactly the same physical values for the lengths L (0.435 m - 2.130 m) for the conical pendulum, mass m = 0.1111 kg, and with the local value of the acceleration due to gravity g = 9.789 ms[superscript…

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.

Dean, Kevin; Mathew, Jyothi – European Journal of Physics Education, 2016

A theoretical analysis is presented, showing the derivations of seven different linearization equations for the conical pendulum period "T", as a function of radial and angular parameters. Experimental data obtained over a large range of fixed conical pendulum lengths (0.435 m-2.130 m) are plotted with the theoretical lines and…

Restricted Closed Shell Hartree Fock Roothaan Matrix Method Applied to Helium Atom Using Mathematica

Acosta, César R.; Tapia, J. Alejandro; Cab, César – European Journal of Physics Education, 2014

Slater type orbitals were used to construct the overlap and the Hamiltonian core matrices; we also found the values of the bi-electron repulsion integrals. The Hartree Fock Roothaan approximation process starts with setting an initial guess value for the elements of the density matrix; with these matrices we constructed the initial Fock matrix.…

Koutandos, Spyridon – European Journal of Physics Education, 2013

In this article we examine cases of more classical and less classical nature compared to results found by quantum mechanics and attribute a form of Free Energy discontinuity for each case within a boundary layer. The concept of a boundary layer is broadened as to include areas of first or second variations of the Gibbs free energy. It is…

Matehkolaee, Mehdi Jafari; Majidian, Kourosh – European Journal of Physics Education, 2013

In this paper we have calculated the work of friction force on the arbitrary path. In our method didn't use from energy conservative conceptions any way. The distinction of this procedure is that at least do decrease measurement on the path once. Thus we can forecast the amount of work of friction force without information about speed of…

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,…

Sazonov, Sergey N. – European Journal of Physics Education, 2013

The purpose of this article is to give the intelligible procedure for undergraduate students to grasp proof of the fact that the magnetic field outside the hollow superconducting sphere (superconducting shell) coincides with the field of a point magnetic dipole both when an uniform external magnetic field is applied as when a ferromagnetic sphere…

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…

Singh, Satya Pal – European Journal of Physics Education, 2013

In this paper of I have reviewed the test done for validating the special theory of relativity using masers and lasers in last one century. Michelson-Morley did the first experimental verification for the isotropy of space for the propagation of light in 1887. It has an accuracy of 1/100th of a fringe shift. The predicted fringe shift on the basis…

Garcia Trujillo, Luis Antonio; Ramirez Díaz, Mario H.; Rodriguez Castillo, Mario – European Journal of Physics Education, 2013

Solving the position of a simple pendulum at any time is apparently one of the most simple and basic problems to solve in high school and college physics courses. However, because of this apparent simplicity, teachers and physics texts often assume that the solution is immediate without pausing to reflect on the problem formulation or verifying…
