Calculators

Calculates the shortening of an object's length as measured by an observer moving relative to it (Special Relativity).

Calculates the magnification power of a lens based on focal length or object/image distances.

Calculates the capacitance of various capacitor configurations.

Calculates the magnetic field strength at a distance from a long, straight wire carrying current.

Calculates the mechanical advantage, output force, or output distance of a pulley system based on input parameters.

Calculates pressure, velocity, or height in a fluid flow system using the Bernoulli equation, based on the principle of conservation of energy.

Calculates the change in frequency of a wave (sound or light) due to relative motion between the source and observer.

Calculates the electric field strength created by a point charge.

Calculates the speed at which an object orbits around another body, based on the mass of the central body and the orbital radius.

Calculates battery capacity (e.g., in mAh or Wh) based on voltage and charge/discharge characteristics.
