2D Magnus Effect — Ball Spin Trajectory Simulator

2D side-view Magnus-effect trajectory simulator: real F = S·(omega x v) Magnus lift combined with gravity and quadratic drag, numerically integrated so spin rate and direction genuinely bend the flight path. Compare spin vs no-spin trajectories live.

This 2D companion to the 3D Magnus Effect laboratory numerically integrates the real Magnus force equation, F = S·(omega x v), together with gravity and quadratic air drag, so that topspin, backspin and sidespin genuinely curve a launched ball's trajectory by the physically correct amount and direction — nothing here is a scripted or pre-baked curve. Adjust spin rate, spin axis, launch speed and angle, and compare the resulting flight path against a no-spin reference trajectory drawn at the same time.

⚙ Under the hood

2D side-view Magnus-effect trajectory simulator: the real F = S·(omega x v) Magnus lift force combined with gravity and quadratic air drag, numerically integrated so spin rate, spin axis and launch conditions genuinely bend the flight path. Adjust spin, axis (backspin/topspin vs sidespin), speed and launch angle, and compare against a live no-spin reference trajectory.
