Circular motion is embedded in many circus tricks, and is also one of the most challenging topics for both students and teachers. Previous studies have identified several misconceptions about circular motion, and especially about the forces that act upon a rotating object. A commonly used demonstration of circular motion laws by physics teachers…

Purpose: A method for controlling for sex-based differences in measures of hyoid movement using an internal anatomical scalar has been validated in young healthy individuals. Known anatomical changes with aging necessitate validation of this methodology in a mixed-age sample. The primary aim of this study was to validate a method for controlling…

In this work we study the motion of a small metal ball along an inclined multi-slotted track. Specifically, the effect of the slot width on the ball speed at the lower part of the track is analyzed in detailed both analytically and experimentally. Experimental results are in satisfactory agreement with the theoretical model.

This paper describes an experiment with two touching rotating disks, whose movement is followed by video analysis. Within the disks' movements, there are intervals with sliding and intervals without sliding, that is, intervals with frictional forces between the touching surfaces and intervals without it. This system configuration allows for…

Students hold a variety of initial (mis)conceptions that are inconsistent with scientific knowledge and hinder their physics learning. The initial (mis)conceptions could coexist with the scientific ones, even after a conceptual change. Inhibitory control may help overcome initial (mis)conceptions. This study investigated if and how inhibitory…

The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

Young children's colouring activities are an educational resource, providing an opportunity for children to express their feelings about the people and objects in their lives. To our knowledge, no systematic empirical research has yet addressed the question of how individualised children's colouring materials with a healthy message impact physical…

The study of robotics has become a popular course among many educational programs, especially as a technical elective. A significant part of this course involves having the students learn how to program the movement of a robotic arm by controlling the velocity of its individual joint motors, a topic referred to as joint programming. They must…

The study aimed to investigate the effect of embodied learning on children's literacy skills and whether the activities were particularly beneficial for children at risk for reading difficulties. We conducted a randomized controlled trial during 4 weeks for grade 1 children (n = 52, age = 7.1). Children were randomly assigned to receive regular…

Jigsaw-IV Problem-solving method is innovative active learning instruction used to improve college student's learning. The main purpose of the study was to investigate the effect of Jigsaw-IV problem-solving instruction on preservice physics teachers' (PSPT) procedural knowledge in college of teacher education in the Southern nation nationality…

Objective: Prephonatory vocal fold angle trajectories may supply useful information about the laryngeal system but were examined in previous studies using sigmoidal curves fit to data collected at 30 frames per second (fps). Here, high-speed videoendoscopy (HSV) was used to investigate the impacts of video frame rate and sigmoidal fitting strategy…

"FORE!" Those four letters are often the only thing that alerts spectators attending golf tournaments of danger heading their way. With professional golfers swinging the golf club at upwards of 120 mph, sending the ball an average of 295 yards (Wilco, 2018), and with professional long drive competitors swinging up to 150 mph, a small…

The article presents the results of an experimental study on the motion of a neodymium magnet on an inclined duralumin plate. During experiments, the time of motion was measured, and the steady-state velocity of the magnet motion was determined. To measure the time, a robotic set was used, which made it possible to measure the time of the motion…

Oscillatory motion with damping proportional to the velocity is part of all upper-class physics courses and some introductory courses; however, the emphasis is primarily on the free amplitude decay. Microelectromechanical (MEMs) accelerometers allow the acceleration to be directly measured and the velocity and displacement to be derived from it.…

The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…
