Block on an incline
Interactive 3DSlide the block down the ramp — steeper ramps accelerate it faster, exactly as g·sinθ predicts.

Study notes
A 2 kg block slides down a frictionless 30° ramp (g = 9.81 m/s²). Acceleration along the ramp: a = g·sin30° = 9.81×0.5 ≈ 4.9 m/s² — independent of the mass. After sliding 4 m: v² = 2·a·s = 2×4.9×4 → v ≈ 6.3 m/s, the same speed as falling vertically through 4·sin30° = 2 m.
