Physics

Physics calculators for velocity, force, pressure, density, energy, work, power, motion, gravity, frequency, resistance, and Ohm’s law.

Potential Energy Calculator

Use our Potential Energy Calculator to find gravitational or elastic potential energy using mgh or ½kx². Get instant results in J, kJ, Wh, kWh, and ft·lbf.

Work Calculator

Use our Work Calculator to find work done from force, distance, and angle or from mass, gravity, and height. Get results in J, kJ, Wh, kWh, and ft·lbf.

Work and Power Calculator

Use our Work and Power Calculator to find work from force and distance or lift, then calculate power in watts, kW, and horsepower from time.

Projectile Motion Calculator

Use our Projectile Motion Calculator to find time of flight, range, maximum height, time to peak, and velocity components from speed, angle, height, and gravity.

Free Fall Calculator

Use our Free Fall Calculator to find time, distance, final velocity, and average speed from height or time with gravity presets and unit conversion.

Force Calculator

Use our Force Calculator to find force from mass and acceleration with F = ma. Get instant results in newtons, kilonewtons, and pounds-force.
