Serve Lab, a Tennis Serve Simulator
An interactive model for exploring how tennis-serve speed, contact position, aim, air resistance, and spin affect the ball’s flight.
Field notes
Serve Lab recalculates launch direction whenever the user changes a serve variable, keeping the selected landing target fixed rather than modeling random miss patterns. Its controls separate contact height from how far ahead of the baseline the ball is struck, and separate vertical, sidespin, and longitudinal spin. The page also exposes a drag estimate of 0.55 and distinguishes net clearance from serve-in probability, giving users several useful guardrails for interpreting the visualization.
