🔬 Canvas A — Virtual Lab Bench

Pure-JS simulators. Drag sliders to explore. (Phase 10.2)

Simple pendulum (small-angle)

Length L (m): 1.00 θ₀ (deg): 20 g (m/s²): 9.81

T ≈ 2π·√(L/g). Watch how period scales with √L.

v₀ (m/s): 20 angle (°): 45

Range R = v²·sin(2θ)/g, max at 45°.

R (kΩ): 1.0 C (μF): 10 V (V): 9.0

V_C(t) = V·(1 − e^(−t/RC)). Time constant τ = RC.

f (cm): 10 s (cm): 20

1/s + 1/s' = 1/f. Negative f = diverging.
