Cross, Rod – Physics Education, 2022
Experimental results are presented concerning the motion of a ball that bounces up an incline a few times then bounces back down again. The number of bounces up the incline is typically small since the speed of the ball in a direction parallel to the incline decreases rapidly, not only during each bounce but also while the ball is in the air. The…

Hitier, Mathilde; González-Martín, Alejandro S. – International Journal of Research in Undergraduate Mathematics Education, 2022
Of the many disciplines that rely on calculus, physics is among those with the strongest connections to this branch of mathematics. For instance, the derivative--one of the key notions of calculus--is used to describe velocity and acceleration, which play a central role in mechanics. In post-secondary education, in particular at the college level,…

Heck, André; Uylings, Peter – Physics Education, 2020
The fact that a bungee jumper can reach an acceleration greater than the acceleration of gravity is, also from a physics point of view, intriguing. Taking only gravity into account, it can be explained by applying conservation of energy or by deriving carefully the equation of motion in a Newtonian approach. In this article we show how it can be…

Palacios Gómez, Jesús; Villagómez, Roque André Eleazar Arroyo – Physics Teacher, 2023
Here, a relatively simple laboratory experiment of a physical pendulum, suitable for students of science and engineering in the first courses of university physics, is presented to illustrate its dynamic behavior and to determine its inertia moment. To this end, a long wooden rod of length L = 99.8 cm and cross-section radius R = 1.73 cm was used…

Cross, Rod – Physics Education, 2022
The trajectory of a ball rolling across an inclined plane was recorded on video film to determine if it followed a parabolic path as others have suggested. The challenges in this case were (a) to determine the magnitude and direction of the friction force on the ball, (b) to determine the effect of the friction force on the trajectory and (c) to…

Li, Tiandong; Zhu, Ruotong; Jin, Huilin; Yang, Hongchun; Wu, Minghe; Teng, Baohua – Physics Teacher, 2021
At the undergraduate level, the composite motion of simple harmonic vibrations has always been the main content of physics as well as several other scientific disciplines. Many textbooks tell us clearly that when the frequency ratio [omega][subscript 1]/[omega][subscript 2] of two perpendicular vibrations is simple integer ratio n[subscript…

Forringer, Edward – Physics Teacher, 2021
When authoring physics problems, professors may develop an intuition for how much information they need to provide such that the problem has a unique answer and is not over constrained. It is an open question as to whether using intuition leads to a sufficiently broad range of problems. In this paper we discuss a systematic way of authoring…

Wells, James; Henderson, Rachel; Traxler, Adrienne; Miller, Paul; Stewart, John – Physical Review Physics Education Research, 2020
Investigating student learning and understanding of conceptual physics is a primary research area within physics education research. Multiple quantitative methods have been employed to analyze commonly used mechanics conceptual inventories: the Force Concept Inventory (FCI) and the Force and Motion Conceptual Evaluation (FMCE). Recently,…

Volkwyn, T. S.; Airey, J.; Gregorcic, B.; Linder, C. – Learning: Research and Practice, 2020
A social semiotic lens is used to characterise aspects of representational competence for a discipline such as physics, to provide science teachers with a practical suggestion about how student learning might be organised to develop representational competence. We suggest that representational competence for some areas of science can be…

Chudinov, Peter; Eltyshev, Vladimir; Barykin, Yuri – Physics Teacher, 2022
The study of the motion of a projectile, thrown at an angle to the horizon, is a wonderful classical problem. This issue has been the subject of great interest to investigators for centuries. Currently, the study of parabolic motion, in the absence of any drag force, is a common example in introductory physics courses. The theory of parabolic…

Espinosa, J. A.; Ribas, F.; Lusquiños, F. – Physics Education, 2022
In order to fix some important concepts of Fundamental Physics, either because they are not usually discussed in depth in theoretical classes and much less at laboratories, or because they are not sufficiently developed in textbooks, it is more effective not to tackle them directly, but to propose a mental or practical experiment to attract the…

El-Tawargy, Ahmed S.; Ramadan, Wael A. – Physics Education, 2022
In this work, a simple rocking pendulum, in a circular arc shape, is presented. The idea is to put a rigid arc on a clean flat surface of glass and leave it to oscillate under the effect of a little impulse. Then, the periodic time of this arc pendulum's motion is experimentally determined. The mathematical analysis of the arc's motion is derived…

Adamopoulos, Anastasios; Adamopoulos, Nikolaos – International Journal of Mathematical Education in Science and Technology, 2022
The cases of constant and quadratic damping of free oscillations are missing from standard textbooks, even at college and university level. The case most examined is that of linear damping, the reason being that the student can work out a closed form which describes all stages of motion. The case of constant damping is straightforward to be…

DiLisi, Greg – Physics Teacher, 2019
The author, Greg DeLisi, a professor at John Carroll University, is always looking for ways to bring current events into his introductory physics classroom or laboratory. He is especially interested in finding examples where basic principles of physics can be used to cast skepticism on assertions made by celebrities, politicians, or professional…

Riggs, Peter – Physics Teacher, 2021
There are plenty of contributions in the physics literature on the subject of standing waves. What seems to be missing is an accessible, quantitative account of standing waves on a circular path at a level appropriate for undergraduate physics courses. In order to rectify this absence, a straightforward, concise, mathematical description of…
