How it works

The ball is a point mass launched with an initial velocity split into aim (yaw), elevation and power, then integrated step by step under three real forces: gravity, quadratic air drag, and the Magnus force from sidespin.

a = g + F_drag/m + F_magnus/m
F_drag  = -½ ρ C_d A |v| v
F_magnus = k_m · ω × v   (ω = sidespin about the vertical axis)

Aim / Power / Elevation — set the launch velocity vector, exactly like the plant-foot angle and strike speed of a real kick.
Curl — sidespin (rev/s) about the vertical axis. Positive curls the ball's path to the right as it travels; the faster the ball moves, the stronger the sideways Magnus push, which is why a curling free kick "bends" more in the middle of its flight than at the very start.
Drag — grows with the square of speed, so a hard-struck ball loses pace faster in absolute terms than a soft one, flattening the usable power range.
Target ring — the classic free-kick aiming points: the corners a keeper struggles to reach. Your miss distance is measured from the ball's crossing point on the goal-line plane to the ring center.

Real-world relevance: this is the same drag + Magnus model used to explain famous banana kicks (e.g. Roberto Carlos' 1997 free kick) and is the standard simplified physics behind football trajectory analysis and broadcast ball-tracking graphics.
