Tap a tile to add or remove it. Drag items on the bench; focus one and use arrow keys. The mass set loads the bob, the clamp changes the string length, and the light gate times each swing.

Changing a value resets the swing. Model: θ″ = −(g/L) sin θ − (b/mL²) θ′, integrated with fixed-step RK4. Period shown is measured from the simulation, not from a formula.
Angle θ (°) against time t (s), last 12 s. Reference small-angle period: — s.
