The record

Purpose: myPhysicsLab provides JavaScript classes for building real-time interactive animated physics simulations.
Interactive simulations: The site offers simulations that animate in real time and let users drag objects or change parameters such as gravity.
Simulation range: The site lists simulations including pendulums, springs, colliding blocks, roller coasters, billiards, and molecular models.
Customization: Users can customize simulations with EasyScript or JavaScript using a browser and text editor.
Sharing: The share button creates a URL whose embedded EasyScript reproduces the simulation setup.
Data access: Users can retrieve numeric simulation data through VarsHistory, JavaScript, or collision-data scripts.
Offline use: The site says downloadable versions can be used to show simulations offline.
Source and license: The software is open source under the Apache 2.0 License, with source code on GitHub.
Build requirements: Building from source requires TypeScript, esbuild, Perl, and GNU Make.
Audience: The simulations include explanations of their underlying mathematics and the site describes the project as an online science museum effort.
Measurement limits: Simulation units are dimensionless and must be used consistently within each simulation.
Security and compliance: The official pages opened describe the software and license but do not state security certifications or compliance claims.
Simulation library: The site lists around 50 simulations, including pendulums, springs, collisions, roller coasters, and rigid-body examples.
License: The software is open source under the Apache 2.0 License, and its source code is available on GitHub.
