In this article we find the thermodynamics of some large N particles systems and some small N particles classical systems using micro canonical ensemble. Small N particle systems are seldom done in textbooks, since statistical mechanics(SM) systems work for large N systems. We show that small N systems will help the students to get an insight…

Teaching upper division statistical physics can often be clouded by the theory and complex examples used. To better help students appreciate the fundamental statistical concepts and how they are connected to thermodynamic principles this paper suggests using a simple abstract model. Using Atkins' Model students can see these ideas clearly…

The question of the sources of electric and magnetic fields and their causes has been discussed extensively in the literature over the last decades. In this article, we approach this problem from the unified treatment of electromagnetic fields emphasizing the role of their sources in accordance with the cause-effect relationships. First, we…

The question of whether Faraday's flux law is universal or whether there are exceptions has long been controversial. This discussion seemed to have recently concluded in favor of the generality of Faraday's Flux Law. The present article raises this question again with the aid of some rather simple measurements carried out on a Faraday generator.…

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…

When deriving the equation describing the transverse motion of a one-dimensional vibrating elastic string, introductory physics textbooks often assume constant tension and/or small amplitude vibrations. However, these simplifying assumptions are not only unnecessary, but they overlook the elastic nature of the tension and yield an inconsistent…

In the light of own measurements on a Faraday generator, the well-known theories concerning Unipolar Induction and the Faraday paradox seem to be problematic. On the other hand, all results obtained, and all other processes described as a paradox in connection with the Faraday generator can be explained without contradiction based on the theory of…

Lab activities are a vital part of physics courses, providing students with hands-on experiences of classroom topics. At the same time, building self-efficacy is vital to student learning and retention; however, females traditionally have lower self-efficacy in STEM fields. This research explores the role of gender and the changes in interest in…

The cosine theorem is used in solving triangulation problems and in physics when solving problems of addition of unidirectional oscillations. However, this theorem is used only for the analytical calculation of triangles or when solving problems of adding two oscillations. Here we propose a generalization of the cosine theorem for the case of…

In this work a review of the research on augmented reality (AR) and its use of the learning of physics in the classroom is carried out. These two concepts of technology and learning are interrelated. Teachers have pre-teaching concepts and methods (conceptual changes), with the aim of having a deeper understanding of physical concepts that occur…

Electric charges and magnetic poles are often confused in the minds of students. It is convenient to remind them that they only interact when they are in relative motion. The force F on a charged particle q moving with velocity V in a magnetic field B is given by F = qVxB. By Newton's Third Law, the force on magnet producing the field B is equal…

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.

The paper presents an assessment of the impact of teaching physics using the Inquiry Based Science Education (IBSE) method on the level of competence and knowledge of primary school students in Poland (second educational stage). The method is based on the teacher-inspired teamwork of students to solve experimental physical problems. This results…

This research is a descriptive study that aimed to investigate STEM competencies of science and mathematics preservice teachers. For this purpose, a group of science and mathematics preservice teachers were asked to design and conduct parachutes covering the topics of movement (free fall, air resistance and lift force) in the course of physics I.…

Based on a publication of Assis, where the most straightforward and oldest motor is described, first constructed by Ampère, a simple experiment is added to demonstrate once again, why published explanations about its principle of operation and especial the kind how Newton's 3rd principle is used has to be rejected. Ampère's description of his…
