Robertson, Bill – Science and Children, 2014
Defining friction and asking what causes it might seem like a trivial question. Friction seems simple enough to understand. Friction is a force between surfaces that pushes against things that are moving or tending to move, and the rougher the surfaces, the greater the friction. Bill Robertson answers this by saying, "Well, not exactly".…

Hinrichsen, Peter F. – Physics Education, 2018
The advantages of deriving the coefficient of kinematic friction from measurements of the damping of oscillatory motion have recently been described. The measurement of the acceleration rather than displacement has the advantage that, as well as the linear amplitude decay, the acceleration discontinuities due to the friction reversal can be…

Vera, Francisco; Fernandez, Nicolas; Ortiz, Manuel – Physics Teacher, 2018
In this paper we describe a simple alternative to the telephone book friction experiment, a classic demonstration where a small force (generated for example by the bending of the outer pages) is amplified by the large number of surfaces in contact, resulting in a huge maximum static friction force that has to be counterbalanced in order to…

Canlas, Ian Phil – Research in Science & Technological Education, 2021
Background: Understanding students' preconceptions is an important initial step towards a successful and meaningful learning in physics. This is more relevant and important especially for concepts that are introduced formally as early as preschool including friction. Visual representation maybe often used as an aid to teaching, however,…

Cross, Rod – Physics Education, 2018
A ball that rolls without sliding down an inclined plane requires a small static friction force to prevent the ball sliding down the incline. The magnitude of that force is investigated by considering the force needed to prevent the contact point from slipping.

Parra, Saro Lozano; Bakker, Cok; van Liere, Lucien – Journal of Curriculum Studies, 2021
Research shows that teachers and educators struggle to act when conflict appears in the classroom. This article argues that (political) conflict should not be avoided or eradicated. Teachers should enable conflict and attend to their pupils in the process, in order to enable further understanding of each other and their differences, as part of…

Cross, Rod – Physics Education, 2020
Two balls on an incline can remain at rest if friction between the balls prevents them rolling down the incline. Results with various balls are presented to show how ball mass, diameter and friction affects the outcome. A stack of four identical balls is also examined.

Maslova, K.; de Jesus, V. L. B.; Sasaki, D. G. G. – Physics Education, 2020
In general, undergraduate experimental physics laboratories do not usually have experiments designed to address rolling friction and to measure the value of the rolling friction coefficient. This work explores an experiment, which has the potential to arouse students' curiosity about rolling friction by addressing a counterintuitive aspect of the…

Pathak, Praveen; Patel, Yogita – Physics Education, 2020
A phone emitting sound of a fixed frequency is sliding on an inclined plane and approaching a second phone kept at the bottom of the plane. The detected frequency versus time data by the second phone are used to calculate the acceleration of the sliding phone. The primary objective of this paper is to calculate the sliding friction between the…

Fontana, Ethan; Yeung, Chuck; Hall, Jonathan C. – Physics Teacher, 2020
Measuring the acceleration due to gravity g is a part of most introductory physics classes. A standard method to do so is by using a ticker tape timer. However, frictional forces are usually not included in the analysis even though friction leads to an acceleration significantly smaller than "g." In this note, we show how to obtain…

Larsson, Maria; Mårtensson, Katarina; Price, Linda; Roxå, Torgny – Teaching & Learning Inquiry, 2020
While educational research and the Scholarship of Teaching and Learning (SoTL) are overlapping fields, over time there has appeared considerable friction between the two. There are claims that educational research has been tainted by SoTL's emergence and that those engaged in SoTL lack adequate training. They maintain that those engaged in SoTL…

Neilson, Drew; Campbell, Todd – Physics Teacher, 2017
Through examining the day-to-day work of scientists, researchers in science studies have revealed how models are a central sense-making practice of scientists as they construct and critique explanations about how the universe works. Additionally, they allow predictions to be made using the tenets of the model. Given this, alongside research…

Hollett, Ty; Luo, Siyuan; Turcotte, Nate; Ramsay, Crystal; Stubbs, Chris; Zidik, Zac – E-Learning and Digital Media, 2020
This article examines embodied interaction in a virtual reality learning environment. Studies of embodied interaction in immersive learning environments, like virtual reality, tend to treat all bodies the same without considering the nuanced cultural histories those bodies have with being mobile, especially within--and beyond--technology-mediated…

Lukovic, Milentije – Physics Teacher, 2019
Friction is one of the common forces that affect our everyday life and one of the oldest problems studied in physics. An interpretation of its nature is included in all general physics courses, in both high school and college. The desire and need to better understand it guided a long list of scientists who devoted themselves to the study of…

Corpuz, Edgar De Guzman; Rebello, N. Sanjay – Research in Science Education, 2019
The first phase of this multiphase study involves modeling of college students' thinking of friction at the microscopic level. Diagnostic interviews were conducted with 11 students with different levels of physics backgrounds. A phenomenographic approach of data analysis was used to generate categories of responses which subsequently were used to…
