About VS Lab
VS Lab is an educational physics site for learning motion, conservation laws, oscillation, and nonlinear dynamics through interactive browser experiments.

The site focuses on learning value rather than short summaries. A page is complete only when it gives a learner something to control, something to measure, and an explanation that connects the result to physics.
The experiments run deterministic physics models in the browser and expose parameters such as gravity, length, mass, damping, restitution, angle, and friction. Measurements are shown beside the animation so each page can work like a guided lab.
Explanations connect definitions, equations, units, assumptions, and common misconceptions. When a model is approximate, the page states the approximation instead of presenting the animation as exact engineering data.
The primary audience is students, teachers, and self-learners who want a quick way to test a mechanics idea before or after studying the formal derivation.
