GravityLab nga ThienBoss884

GravityLab is an interactive 2D physics sandbox that runs locally in Firefox.

Drop balls, boxes, heavy objects, and static platforms into the simulation, then drag objects to throw them through the scene. Gravity, bounce, friction, and simulation speed can be adjusted while the world is running.

GravityLab includes Earth, Moon, Jupiter, zero-gravity, and changing-gravity presets, along with tools for spawning multiple objects and applying an outward blast to the scene.

The simulation does not require an account, network connection, or external service.
