🪂 Drag Coefficient 2D — Terminal Velocity (2D)

2D Canvas simulator: drop a sphere, cube or streamlined body through air or water, watch the drag and gravity force vectors, and read the live Cd-vs-Reynolds-number curve and terminal velocity.

⚙ Under the hood

A 2D companion to the drag coefficient simulator: drop a sphere, cube, or streamlined body through air or water and watch gravity and aerodynamic drag force vectors act on a falling object. A live Cd-vs-Reynolds-number log-log graph tracks the shape's real drag-crisis curve, and the HUD reports live drag coefficient, Reynolds number, velocity, and the terminal velocity computed from the force balance between gravity and drag.
