Physics

Find average velocity, 1D constant-acceleration results, and 2D velocity magnitude and angle with clear units and sign checks.

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

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

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

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

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

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

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

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

Find impulse, momentum change, velocity change, average force, or time in 1D with clear SI units and direction (sign) help.
