Lozovenko, O.; Minaiev, Yu; Lutai, R. – Physics Education, 2022
The purpose of this publication is to present a novel approach to the demonstration of the Dzhanibekov effect. The main idea of our version is to use a lightweight spinning top of a spherical external form but distinct principal moments of inertia floating in the upward flow of air. As a result, the Dzhanibekov effect can be easily demonstrated…

Santosa, I. E. – Physics Education, 2021
A simple measurement of the refractive index of a liquid has been performed using a spherical lens. This lens is a spherical shape flask containing the liquid under study. Parallel pointer laser beams are directed to the lens to obtain the back focal length of the lens. The focal point is determined visually or using the Tracker software to…

Neel, Matthew S. – Physics Education, 2022
Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

Coramik, Mustafa; Özdemir, Erdogan – Physics Education, 2021
In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the…

Satriawan, Muhammad; Liliasari, Liliasari; Setiawan, Wawan; Abdullah, Ade Gafar – Physics Education, 2020
This research aims to develop an ocean wave energy converter kit from low-cost materials as a teaching tool. The kit is developed using the working principle of a wave energy converter that uses a buoy as a system drive and a weight balancer that is connected to a chain. The dimensions of the kit are 6.7 × 0.3 × 0.4 m (length × width × height)…

Mayer, V. V.; Varaksina, E. I. – Physics Education, 2020
For conducting laboratory experiments on Fresnel diffraction, the use of a simple point light source from an LED and the application of a modern smartphone for photographing the diffraction patterns are proposed. The developed devices allow the experiments to be carried out under normal laboratory lighting.

Chen, Yu; Lee, Jiwon; Moon, Su Jin; Jung, Pyung Kang; Cho, Youngsaeng; Kim, Jung Bog – Physics Education, 2021
This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying…

Walkup, John R.; Key, Roger A.; Duncan, Sean Patrick; Sheldon, Avery E.; Walkup, Michael A. – Physics Education, 2020
Error analysis consumes much of the focus in introductory physics labs. Catastrophic cancellation is a spike in error that occurs when subtracting two measurements of roughly equal magnitude. Often termed "loss of significance" or "subtractive cancellation," this effect can easily relegate experimental results to utter…

Eadkhong, Thammarong; Sirisathitkul, Chitnarong; Danworaphong, Sorasak – Physics Education, 2022
Video analysis is carried out for one-dimensional motion and collision experiments using Tracker. Physical variables, i.e. displacement, time, and velocity, can be deducted from the analysis and allows one to connect them to the equation of motion and energy conservation. Corresponding equations of motions are given without neglecting the effect…

Hachmi, Ali; El Hadi, Mohammed; Essaadaoui, Rachid; Mommadi, Omar; Ouariach, Abdelaziz; El Moussaouy, Abdelaziz – Physics Education, 2022
The Arduino board and its communication with several sensors are becoming more and more popular in the physical science community. They offer inspiring possibilities for learning different physical concepts. In this article, we focused on creating a very practical educational system for experimenting with diffraction of laser light and graphically…

El Hadi, M.; Ouariach, A.; Essaadaoui, R.; El Moussaouy, A.; Mommadi, O. – Physics Education, 2021
In this work, we have developed an alternative device composed by an Arduino board and an INA219 sensor to experimentally obtain the mathematical formulas describing the charge and discharge of the capacitor for educational proposes. We have obtained excellent agreement between theoretical prediction and experimental measurements. The INA219 DC…

Atkin, Keith – Physics Education, 2019
This paper was inspired by the work of a previous contributor on the subject of modelling plague epidemiology by comparing it to the physics of series radioactive decay, RC transients, and fluid dynamics. An Arduino-based experiment to illustrate the fluid-dynamical case is described. Attention is drawn to important differences between systems…

Espindola, P. R.; Cena, C. R.; Alves, D. C. B.; Bozano, D. F.; Goncalves, A. M. B. – Physics Education, 2018
The study of buoyancy becomes very interesting when we measure the apparent weight of the body and the liquid vessel weight. In this paper, we propose an experimental apparatus that measures both the forces mentioned before as a function of the depth that a cylinder is sunk into the water. It is done using two load cells connected to an Arduino.…

Velloso, M.; Arana, M.; Acioly, V.; Santos, A. C. F. – Physics Education, 2021
The COVID-19 Pandemic interrupted university activities at the beginning of the first semester of 2020, forcing the academic community to reinvent itself to meet the determinations of social isolation. The use of assistive technologies such as information and communication technologies has never been more welcome. However, for a college student…

Singh, I.; Khun Khun, K.; Kaur, B. – Physics Education, 2018
Excel spreadsheets are used as an excellent tool in physics laboratory experiments related to wave optics. This paper presents a simple way to simulate diffraction of waves through a slit using Excel spreadsheets without any tedious programming. These simulations are used to visualize the effect of variation of different parameters such as number…
