Calculators

Calculates sound intensity levels in decibels (dB) or changes in dB based on power or intensity ratios.

Calculates the maximum theoretical efficiency of a heat engine operating between two temperatures.

Calculates the induced electromotive force (EMF) in a circuit based on Faraday's Law of Induction. This law states that the EMF is proportional to the rate of change of magnetic flux through a circuit.

Calculates the change in velocity (delta-v) a rocket can achieve based on propellant mass and exhaust velocity.

Calculates the minimum speed needed for an object to escape the gravitational influence of a celestial body.

Calculates the kinetic energy of electrons ejected from a material when light shines on it, based on photon energy and work function.

Calculates the energy of a single photon based on its frequency or wavelength (E=hf or E=hc/λ).

Calculates the focal length, object distance, or image distance for a thin lens using the thin lens equation: 1/f = 1/do + 1/di.

Calculates the kinetic energy an object possesses due to its rotation (KE = 1/2 Iω²).

Calculates the energy stored in a deformed elastic object, like a spring (PE = 1/2 kx²).
