Équations du Mouvement
m*ax = -0.5 * ρ * Cd * A * vx * |v|
m*ay = -mg - 0.5 * ρ * Cd * A * vy * |v|
|v| = √(vx² + vy²)
g = 9.80665 m/s², ρ = 1.225 kg/m³
The units and constants behind this shot
A projectile is set by four quantities. Follow any of them into the converter, or into the constant that bends the path back down.

Ranges are calculated live from R = v₀²·sin(2θ)/g (no air resistance). * Earth's value is the defined standard gravity g₀; the others are NASA surface-gravity figures.
Why 45° throws the farthest
Range is v₀²·sin(2θ)/g, and sin(2θ) peaks when 2θ = 90°, so θ = 45°. That holds only in a vacuum: switch on air resistance in the simulator and the best angle drops to roughly 35–40°, because a flatter shot spends less time being slowed down.
