Calculators

Calculates the heat absorbed or released during a phase change (melting, boiling) at constant temperature (Q=mL).

Combines calculations for both work done and the rate at which it is done (power).

Calculates the intensity or effect of something according to the inverse square law. This law states that the intensity of a phenomenon is inversely proportional to the square of the distance from the source.

Calculates power as the rate at which work is done or energy is transferred. You can calculate power using work and time (P = W/t) or force and velocity (P = Fv).

Calculates stress as force applied per unit area within a material (σ = F/A).

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

Calculates the ratio of useful output energy or power to the total input energy or power, often as a percentage.

Calculates the centripetal force required to keep an object moving in a circular path.

Calculates the volume or mass of fluid passing a point per unit time.

Calculates the energy equivalent of mass (or vice-versa) using Einstein's famous equation.
