Aristotle's wheel paradox is a fascinating example of a classical puzzle that can pique a student's interest. The existing explanations in the literature are limited to discussions of the wheel trajectory; in this paper, we study the paradox from the viewpoint of motion decomposition, an approach we consider more intuitive. The motion of the point…

We propose a method to measure the speed of sound in air using a motion detector. The experiment is based on the principle of a motion detector used to measure distances. This device measures the time of flight of alternating ultrasonic waves between the observer and the target. By assuming a fixed speed of sound, the time of flight can be…

There has been little written about the ways in which teachers understand draggable geometric objects in a dynamic geometry environment with respect to variance and invariance--two important mathematical ideas related to the development of spatial perception and geometric reasoning. In this article, we investigated such understanding from two…

The center of mass (CM) is an abstract quantity but essential as a reference point used to understand the position and movement of an object or a system of objects. Many researchers have used video recordings to analyze and understand the movement of objects in a system. In a system with colliding objects, the motion can be obtained precisely from…

The use of toys as teaching aids in physics classrooms has a rich history, and the role of play in science education is a well-established line of research. Much of what has been written on the topic has included discussions of specific toys and the implications of using those toys to teach physics. One of the toys from my childhood that seems to…

In this paper, we take an interest in a recently emerged 'DIY sports infrastructure' in a Belgian city: the Open Gym. The purpose of our inquiry is to contribute to the literature regarding sports pedagogy by developing theoretical notions, based on empirical engagements, that render how these kinds of sports infrastructures could make up…

Spatial updating based on self-motion cues is important to navigation in the absence of familiar landmarks. Previous studies showed that spatial updating without vision was automatic. The goal of the current study was to investigate whether ambiguous orientations indicated by visual cues affect spatial updating based on self-motion. Participants…

In this study, flow, both dispositional and state, and movement-based creative processing were investigated in a group of pre-professional and professional dancers (N = 288) who were involved in the creation, rehearsal, and performance of a new dance work(s). Dance is both movement-based and group-based. The Experience of Creativity Questionnaire…

A commonplace sight is seeing other people walk. Our visual system specializes in processing such actions. Notably, we are not only quick to recognize actions, but also quick to judge how elegantly (or not) people walk. What movements appear appealing, and why do we have such aesthetic experiences? Do aesthetic preferences for body movements arise…

The dynamics of a simple pendulum are often presented to undergraduate engineering students in introductory courses in dynamics. It is usually the first dynamic system considered by students that is modelled by a differential equation. This paper presents the standard material given to students. It is fair to say that students are accepting this…

The relativistic addition of velocities is usually introduced early in the study of Einstein's special theory of relativity. The equations are simple enough, but randomly chosen velocities lead to unwieldy calculations that can dishearten the student. This paper presents tables of velocity components in two dimensions, composed of five or fewer…

The dynamics of yo-yo motion are considered in this article. Many textbooks have examined the "rolling" motion of a yo-yo as it moves vertically up or down. However, in the vicinity of the lowest point, a jerk in the string occurs as the center of mass transitions from a linear motion to a pure rotational motion (with respect to the end…

While previous research has highlighted the significance of pedagogical approaches such as story, embodiment, and play for young children's science learning, limited attention has been given to how these three approaches can be integrated into a learning environment to support science learning for young children. Accordingly, this study designed a…

Movement of the body is an essential way to characterise autism, according to diagnostic criteria. However, qualifying descriptions of what autistic movements are, their functions and personal value, are missing from academic literature and clinical guidance. We systematically searched for autistic adults' descriptions of their body and its…

Manual exploratory behaviors during object interaction that form the basis of tool use behavior, are mostly qualitatively characterized in terms of their frequency and duration of occurrence. To fully understand their functional and clinical significance, quantitative movement characterization is needed alongside their qualitative analysis.…
