Our verdict on Walter Fendt Apps on Physics

Walter Fendt Apps on Physics is a free collection of 57 English-language HTML5 simulations for teaching, studying, and demonstrating physics. It is aimed at educators, students, and independent learners who need interactive activities across a wide range of subjects rather than a single specialized simulator. The apps cover mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, relativity, atomic physics, nuclear physics, and solid-state physics. Examples include projectile motion, pendulums, electrical circuits, lenses, ideal gases, radioactive decay, and Bragg reflection.

Breadth is the collection’s defining strength. Mechanics activities address motion, forces, collisions, gravity, and buoyancy, while the wave and optics sections include oscillations, refraction, interference, and diffraction. Thermodynamics activities include ideal-gas processes and the Carnot cycle. This range makes the collection useful for lessons that move between major physics units, especially when a teacher wants a focused interactive demonstration without adopting a larger course platform. The downloadable HTML5 archive also gives users another way to access the collection alongside the web version.

The trade-off is a narrow activity model: the product centers on individual simulations rather than a broader instructional workflow. It does not document authoring tools, assessment features, 3D visuals, or data export, so it is less suited to instructors who need to build custom simulations, collect learner responses, analyze results, or present three-dimensional scenes. Users seeking a free, topic-spanning reference and demonstration library should find the coverage compelling. Those needing structured course management, advanced visualization, or simulation authoring should choose a platform built around those capabilities instead.
