IT'S GOOD!
Split the uprights with 1.4m clearance
🇧🇷 NFL International in Rio
When the NFL visits Rio de Janeiro's iconic Maracanã stadium, coastal Atlantic atmospheric pressure (sea level 1,013 hPa) increases air density compared to Denver or high-altitude venues. Footballs experience 14% higher aerodynamic drag, requiring tighter ball spirals and higher launch velocity for long distance field goals.
📐 Ballistic Physics & Crosswind Drift
An NFL placekick launches with backspin (end-over-end rotation), generating Magnus lift that flattens the ball's descent. Crosswinds pushing against the oblong 11-inch pro football create asymmetric lateral forces, drifting a 50+ yard kick by up to 12 feet off target line.
⚡ Upright Margin of Error
NFL goalpost uprights are exactly 18 feet 6 inches (5.64 meters) apart, resting on a crossbar 10 feet (3.05 meters) above the turf. From 54 yards away, a mere 1.8° deviation in horizontal trajectory turns a game-winning split into an upright "DOINK".
How does this simulator calculate trajectory and upright collisions?
The simulation integrates three-dimensional projectile equations at 60 FPS using Euler integration with real-world drag coefficient ($C_d \approx 0.07$ for tumbling pro football), gravitational acceleration ($9.81\text{ m/s}^2$), and horizontal wind vector drift. The goalpost collision geometry models the crossbar cylinder and twin vertical upright pipes with restitution bounces.
Can I export my kicking session statistics?
Yes! After kicking, click the "Export Log" button in the top navigation. It downloads a full session telemetry summary including distance, aim angle, power, wind velocity, flight time, apex height, and make/miss status.
