Physics

Ramp forces made clear: weight components, normal force, static vs kinetic friction, net force, acceleration, and slip thresholds.

Compute acceleration magnitude from components, delta-v over time, or force and mass. See results in your unit, m/s^2, and g.

Compute projectile max height from speed+angle or v0x/v0y. Includes time to peak and a solve mode for required speed.

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

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

Compute ballistic coefficient using Small-arms (SD/i) or Physics (m/(Cd*A)) methods with clear units and labeling.

Estimate car jump distance, hang time, peak height, and impact angle from speed, ramp angle, and height. Includes solve-for speed or angle.

Solve 1D two-object collisions for final velocities, momentum check, and kinetic energy change (elastic, stick-together, or e).

Find 1D displacement using positions, constant velocity, or constant acceleration, with sign help, units, and formula shown.

Find free fall time, impact speed, and max height with unit choices, sign convention, and an optional terminal-speed air model.
