⚽ Magnus Effect: Ball Spin Physics Simulator - 2D Cross-Section

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.
