Enter the current physics catalog through motion, gravity, waves, sound, fields, circuits, light, and modern-physics benches that still share one compact simulation-first product language.
Physics is still the broadest branch in Open Model Lab, but it no longer needs to hide important topic boundaries. Use this subject page when you want the main physics topics, starter tracks, and best-first concepts framed together before you commit to one branch.
Starter tracks
Start with vector components, move into projectile paths, and then use circular motion to understand how velocity can keep changing direction.
Starts with Vectors and Components across 3 concepts.
Start with one source mass creating a field and potential well, then use that same gravity model to explain circular speed, orbital periods, and the escape threshold.
Starts with Gravitational Fields across 5 concepts.
Start with source charges and voltage, then carry that same circuit story into current, power, branch behavior, and equivalent resistance.
Starts with Electric Fields across 6 concepts.
Cross-subject bridge
Start with vectors as geometric objects on a 2D plane, then carry the same component language into the existing motion-facing vectors bench.
Starts with Vectors in 2D across 2 concepts.
Topics
Best first concepts
Rotate and scale a live vector, decompose it into horizontal and vertical parts, and watch those components drive the same straight-line motion and geometry.
See one repeating system from displacement to acceleration and back again, with the math tied directly to the motion on screen.
A strong first concept for opening concepts without committing to a full track.
Keep one battery and two resistors in view while current, voltage, resistance, Ohm's law, and the contrast between series and parallel all stay tied to one honest circuit.
