- Projectile Motion CalculatorTwo-axis constant-acceleration kinematics (vacuum trajectory)Enter a launch speed, a launch angle and — if the projectile does not start at ground level — a launch height. The calculator…
- Free Fall CalculatorConstant-acceleration kinematics with g = 9.80665 m/s² (standard gravity, NIST SP 330)Drop something from rest and gravity does the rest of the arithmetic. Give this calculator either the height it falls from or…
- Final Velocity Calculator (SUVAT)Constant-acceleration (SUVAT) kinematicsEnter an initial velocity and an acceleration, then tell the calculator whether you know the time the acceleration lasts or the…
- Newton's Second Law (F = ma) CalculatorNewton's second law of motion; SI units per NIST SP 811Pick which of the three quantities you want, enter the other two, and this calculator solves F = ma for it. It also reports the…
- Friction Force CalculatorCoulomb (Amontons) dry friction modelEnter a mass, a slope angle and the static and kinetic coefficients of friction for your material pair, and this calculator…
- Work Done by a Force CalculatorMechanical work, W = F·d·cos θ (SI joule per NIST SP 811)Work in physics means force multiplied by the distance moved in the direction of that force, and this calculator gives it to…
