The Golf Ball Fitter

Model Parameters

Launch Speed

Initial velocity of the golf ball in mph.

v = Ball Speed × 0.44704 (mph → m/s)

Launch Angle

Angle at which the ball leaves the club face.

v_x = v × cos(θ)
v_y = v × sin(θ)

Spin Rate

Determines lift & drag through Magnus effect.

F_lift = 0.5 × ρ × C_L × A × v²

ZIP / Altitude

Adjusts air density for real conditions.

ρ = 1.225 × e^{(-h / 8500)}

Air Density

Calculated from temperature & altitude.

ρ = 1.225 × (273 / (273 + T))

Carry Distance

Trajectory calculated using Newtonian mechanics including drag & lift forces.

m(dv_x/dt) = -½ρC_DA v²
m(dv_y/dt) = ½ρC_LA v² − mg
