# Kinetic Energy Calculator

This kinetic energy calculator calculates the kinetic energy of an object based on the object's mass and the object's velocity, according to the formula shown above. Kinetic energy is the amount of energy which an object possesses while in motion.

To use this calculator, a user just enter's the mass of the object, measured in grams (g), and the velocity, measured in meters per second (m/s). The result of the computation is in unit joules (J).

A kinetic energy calculator can be useful for electronics, especially when viewing it from a more physics perspective, because it can be used to calculate
the kinetic energy of electrons in a circuit. Remember that
current is electrons in motion. So when there is current in a circuit, meaning moving electrons, these electrons have kinetic energy. The opposite of kinetic energy is potential energy,
which are electrons that aren't moving. See the potential energy calculator
to learn more. To calculate the amount of energy that electrons have while in motion, all we have to do is calculate the kinetic energy. We plug in the mass of electrons and
their velocity and we compute the kinetic energy.
