By Trisha Tewari|Updated : June 22nd, 2022

The SI unit of energy is Joule, it is derived by multiplying force by distance. Energy has varied forms such as potential, thermal, kinetic, chemical, and nuclear energy. It can be transmitted from one body to another to numerous ways. The SI unit of energy is credited to be titled after James Prescott Joule.

## How Is The SI Unit Of Energy Determined?

The SI unit of energy is Joule. It is derived by multiplying the force by distance. As per the first law of thermodynamics, energy can never be originated or created and destroyed. It gets transmitted and changes form. Take a look at the derivation facilitated here.

Force= Mass X Accelaration

The SI unit for Force is Newton.

Therefore, Energy= Force X Distance

The SI unit of Distance is metre, henceforth it is expressed as N.m which is equivalent to Joule.

Summary:

## What is the SI unit of Energy?

The SI unit of energy is called Joule, it is credited to be titled after James Prescott Joule. It can be derived by multiplying Force into the distance. The energy can change its form and get transmitted from one body to another. GradeStack Learning Pvt.
