## What is a joule?

Joules is a term commonly used in physics to describe energy. Joules are the standard unit of measurement for energy and work in the International System of Units (SI).

The joule is represented by the symbol “J”

## Joule formula

This calculator used to measure the energy in joules

Energy = 1/2 * m * v^2

Where:

- m = mass of object (kg)
- v = velocity of an object (m/s)
- Energy in joules

## How to calculate the energy in joules

Example1:- A car has a speed of 20 meters per second(m/s) and a weight is 150 kg then calculate kinetic energy in joules

Mass of car = 150 kg

Speed of car = 20 m/s

Kinetic energy(joules) = 0.5 * m * v *v = 0.5 * 150 * 20 * 20 = 30000 joules
