Abstract

Physics experiments play a crucial role in fostering student engagement, serving as a foundation for active learning and critical skill development. Experiments provide hands-on experiences that help students develop problem-solving abilities, scientific reasoning, and collaborative skills. Understanding the trends in experimental physics publications for teaching is essential to assess how this field evolves and to identify research gaps. This study examines the publication trends of experimental physics research for teaching over the past decade (2015–2024) by analyzing 2352 articles from prominent journals, including Physics Education, The Physics Teacher, European Journal of Physics, and American Journal of Physics. The results highlight notable peaks in publication during key periods, such as the COVID-19 pandemic, which accelerated innovation in virtual and remote experimental setups. Mechanics emerged as the most frequently researched topic, while thermodynamics and modern physics were underrepresented, suggesting significant research gaps. The analysis also identifies the transformative potential of technological advancements like smartphone-based tools and augmented reality, which have significantly enhanced teaching methodologies. This study underscores the need for collaborative efforts among researchers, educators, and policymakers to develop accessible, scalable, and innovative experimental approaches.

Abstract

Investigating the motion of solid particles in fluids analyzes the drag force experienced by the particles, depending on parameters such as particle diameter, fluid velocity, density, and viscosity. The Reynolds number, which expresses a fluid's inertia relative to its viscosity, governs the dimensionless drag coefficient, which is critical to understanding drag forces. Terminal velocity, achieved when the force of gravity equals the buoyancy and drag forces of the fluid, is a critical concept often analyzed using the Stokes model. However, differences between theoretical and experimental terminal velocities arise due to oversight of the model's application conditions. Numerical experiments offer controlled conditions to address this, helping predictions align with theoretical models. This research explores the influence of density ratio and particulate diameter on terminal velocity, aiming to support research-based learning for teachers and conceptual understanding for students. Numerical experiments designed by Arbie et al. (2021) investigated two-dimensional particulate configurations, allowing controlled manipulation of parameters. The results show a strong influence of the density ratio and diameter to the terminal velocity, with larger parameter values influencing the Reynolds number and giving rise to differences between theoretical and experimental values. Therefore, careful parameter selection is essential for viscosity experiments, aligning with the objectives and comparability of theoretical models.
