Speed at Any Instant — Recombining the Components

▶ شغّل المحاكاة

Freeze a horizontal throw anywhere and read its velocity triangle: vₓ never changes, vᵧ grows by g every second, and the speed is the hypotenuse, never the sum. 14.7 and 19.6 make 24.5 — and the energy route √(v₀² + 2gh) agrees to the decimal.
