This saved baseball lab computes air density from a pressure-height approximation and absolute temperature. At sea level the pressure term is one hundred one thousand three hundred twenty-five pascals. Sixty-eight degrees Fahrenheit is two hundred ninety-three point one five kelvin. Dividing pressure by two hundred eighty-seven point zero five eight times temperature gives about one point two zero four kilograms per cubic meter. This is a written atmospheric approximation, not weather observation. The source lift coefficient is spin divided by two thousand times point one eight. Two thousand revolutions per minute gives point one eight. Three thousand gives point two seven. At unchanged relative air speed and density this makes the lift term one and a half times larger. Drag and lift are both proportional to relative air speed squared, and wind is subtracted from horizontal ball speed before that calculation. These coefficients are illustrative source assumptions, not validated Statcast prediction. The integrator uses point zero zero five-second steps and updates velocity before position. With hypothetical horizontal velocity one hundred feet per second and acceleration negative ten, next velocity is ninety-nine point nine five and next horizontal displacement is point four nine nine seven five feet. The source clamps recorded final height to zero before its landing interpolation, so its interpolation cannot reconstruct an unrecorded negative endpoint.
