Manifesto
Sport is not random.
Every pass, swing, seam, bounce, strike, edge and miss has a cause. Most sports games hide those causes behind animation, ratings and probability. Ball Physics does the opposite.
We make the invisible mechanics of sport playable.
Deterministic.
The same input produces the same outcome. No hidden dice.
Visible.
Force, spin, drag, timing, contact and decision-making are surfaced, not hidden.
Playable.
Each sport becomes a puzzle you can feel, repeat, improve and understand.
What we refuse
The anti-patterns of modern sports games.
No
Rating sliders
Real physical parameters — mass, angle, spin, drag.
No
Hidden momentum
Every outcome traces back to a force you set.
No
Scripted drama
Tension emerges from mechanics, not from a screenwriter.
No
Probability screens
No percentage curtain. The seam either swings or it does not.
The physics, on the page
three sports · one core
Not a metaphor. The math is illustrated on screen.
football · Magnus lift
F_M = ½ · ρ · v² · A · C_L(ω)
Topspin bends the arc downward; backspin lifts it. Same striker, different spin → different landing zone.
cricket · Seam angle → swing
θ_seam · Re → δ_lateral
Rotate the seam 18° at 34 m/s and lateral displacement is not luck — it is a boundary-layer transition.
baseball · Launch envelope
R = (v² · sin 2θ) / g (with drag)
Exit velocity and launch angle define a landing envelope. Everything else — barrel, spray, hang time — falls out of it.

A note from the lab
Sport is not a story we tell. It is a system we choose not to look at closely enough.
Every pass, seam, edge, bounce and miss has a cause. Ball Physics is the choice to look — and to make what we find playable.

for the Mind.
Weight a 34-metre pass into a 2-metre gap between two defenders closing at 6 m/s. Set body shape, contact point, spin, angle. Watch the arc, drag and Magnus curve resolve — deterministically.

“The pass that curls behind the line is not a stat — it is a vector, a spin axis and a defender who read it a beat too late.”

Field notes
Writing from inside the engine.
Short explainers on the mechanics behind each sport — the physics we model, the questions we chase.
Platform dispatch
New engines. New mechanics.
Once a month, straight from the lab.
A quiet, technical newsletter. Ship notes on the Football, Cricket and Baseball engines. Occasional deep dives on force, seam, spin and timing. No hype.
Physics Fun Fact
Einstein on the pitch.
A moving clock ticks very slightly slower than a stationary one. In principle, a fast-moving ball may finish a match fractionally younger than the players around it — not by much, perhaps trillionths of a second, but enough to remind us that sport is physics all the way down.
