What this model includes
A 12-inch-circumference, 6.5-ounce softball under gravity and optional quadratic air resistance. The drag coefficient is assumed to be 0.40; air density is fixed at 1.225 kg/m³. These are exploratory results, not calibrated predictions for a specific ball or bat.
Flight stops at the first ground or fence contact. A ball above the wall continues to its projected landing beyond the fence. The ball is a point for collision checks. Distance is horizontal travel, and the 3D view uses an orthographic projection.
Player markers provide context. There are no catches, bounces, rolls, wind, spin, pitches, or bat-ball collisions yet. Exit velocity and launch angle are direct inputs.
