Use our Ohm’s Law Current Calculator to find current from voltage and resistance. Get instant results in A, mA, or µA plus power and conductance.

Use our Gravitational Force Calculator to find the force between two masses with Newton’s law of gravitation. Get results in newtons, lbf, and acceleration on each mass.

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

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.

Calculate mechanical work and average power from force, displacement, angle, and elapsed time, with clear joule and watt interpretation.

Calculate mechanical work using force, displacement, and the angle between them, with sign conventions, examples, and unit guidance.

Calculate near-Earth gravitational potential energy from mass, gravitational acceleration, and height relative to a chosen reference level.

Calculate translational kinetic energy from mass and velocity, rearrange the formula, convert units, and explore the squared effect of speed.

Calculate density, mass, or volume with unit conversion, worked examples, and clear guidance about temperature, mixtures, and measurement precision.

Calculate pressure, force, or area with common pressure-unit conversions and guidance about normal force, area, and gauge versus absolute pressure.

Calculate average acceleration from initial velocity, final velocity, and elapsed time while keeping direction, signs, and units consistent.
