Find time of flight, range, and impact speed for a horizontal launch. Includes a target point mode to solve for needed v_x.

Find ground speed from true airspeed and wind, plus WCA, heading, and headwind/crosswind components with a clear wind FROM/TOWARD toggle.

Find friction force, coefficient of friction, or normal force for static or kinetic cases. Includes incline normal-force helper and motion check.

Add 2 to 5 velocity vectors and get resultant x/y components, magnitude, and direction (degrees) from magnitude+angle or components.

Estimate 1/4-mile ET and trap speed from weight and horsepower, or solve the horsepower or weight needed for a target run.

Calculate projectile range, flight time, max height, and impact speed (no air resistance). Also solve for speed or angle on flat ground.

Solve 2D projectile motion (no air resistance): time, max height, range, impact speed, and angles to hit a target distance.

Calculate polar second moment of area J for solid or hollow circles. Optional torsion helper gives shear stress and twist angle.

Calculate muzzle velocity from energy and mass, pressure and barrel geometry, distance and time, or chronograph correction with units.

Calculate momentum, mass, or velocity in 1D or 2D, plus impulse from force and time with unit conversions and clear sign rules.
