Development of Instructional Physics Simulations for Classical Mechanics

We have developed two new physics simulations with learning objectives to address the lack of accessible and satisfactory educational tools for students. Our design process involved researching pre-existing web-based physics simulations and identifying gaps in learning devices for specific physics concepts. Our simulations are coded in JavaScript using the THREE.js library tocreate a 3D interactive environment with orbit controls. The animated frames are optimized for mainstream desktop internet browsers, with future testing aimed at expanding usability to mobile devices. We are currently revising one of the simulations to include an accessible, simplified, and immersive user interface for new learners. The first simulation explores the conservation of angular momentum and how angular velocity changes with factors that vary the moment of inertia caused by internal forces. The second simulation embodies crucial orbital mechanics concepts, such as Kepler's Second Law, conservation of total angular momentum and mechanical energy, and impulsive orbital maneuvers. Our long-term goal is to determine the impact of the simulations on understanding and engagement with the targeted concepts in undergraduate classrooms.
