Physics

Solve Hooke’s law for force, spring constant, or displacement, plus spring energy, work, equilibrium stretch, and SHM period.

Convert kg to newtons correctly with mass-to-weight or kgf-to-N mode, gravity choice, and clear rounding controls.

Calculate force, mass, or acceleration with F = m a, signed 1D forces, unit options, and optional velocity-time acceleration.

Estimate car crash settlement value using multiplier or per-diem pain and suffering, then adjust for fault and policy limits.

Find rolling resistance force (N), watts (W), and trip energy (Wh) from mass, Crr, speed, and grade. Compare setup A vs B.

Estimate sled acceleration, time, and bottom speed on a slope with friction, plus a will-it-slide check and stop distance.

Solve 1D constant-acceleration motion from any 3 SUVAT values with unit choices, sign handling, and clear time-root results.

Calculate terminal velocity, mass, area, or drag coefficient with optional buoyancy and altitude-based air density.

Find projectile time of flight using speed and angle or velocity components, with custom start height, landing height, and gravity.

Calculate projectile motion, landing range, max height, position at time, and target-hit angles with clear feasibility checks.
