Field notes
The landing page is a subject index rather than a long explanation: its links group models under kinematics, forces, energy, rotation, waves, thermodynamics, and electromagnetism. The page describes the models as manipulable, with equations changing when users drag objects or adjust numbers; that behavior is presented in the homepage copy, not demonstrated in the extracted text. A feedback link invites error reports, alongside further reading and donations.
