Challenge 1 of 3
Pull in to catch up
Two salvage pods rotate with a hub. Pull them inward to match the faster station.
Challenge cleared. Continue to unlock the next experiment.Handles also support arrow keys; the sliders offer the same controls.
Match a docking rotation between 2.85 and 3.15 rad/s.

3 stars on your first test; 2 within three; 1 after that. A first clear earns 100 XP plus 10 per star. Better star records earn the difference; repeating a record earns no extra XP.
Your experiment is ready.
Change the moment of inertia of an isolated rotating rig while conserving angular momentum, and distinguish that conservation from kinetic-energy conservation.

The physics behind the game
Change the moment of inertia of an isolated rotating rig while conserving angular momentum, and distinguish that conservation from kinetic-energy conservation.
I = Iₕᵤᵦ + 2mr²; Iᵢωᵢ = I𝒻ω𝒻
Model assumptions. Two equal point-mass pods move symmetrically on a rigid hub. External torque is zero. Motors move the pods and can change rotational kinetic energy; angular momentum remains constant.
