## Joule Fromula

The following formula is used to calculate the total energy in Joules a moving object has.

(K) = 1/2 *(m)*(v)^2

- Where K is kinetic energy in Joules (J)
- m is mass (kg)
- and v is velocity (m/s)

## Joule Definition

A joule is defined as the standard SI unit for energy. The most common uses of the unit joules are for kinetic and potential energy as well as thermal energy.

## How to calculate joules?

How to calculate a joule

**First, measure the mass of the object**Using a scale or formula, determine the mass of the object.

**Next, measure the velocity**Measure or determine the velocity of that same object.

**Calculate**Calculate the total number of joules of kinetic energy the object has using the information above.

**Example Problem #1: **

First, determine the mass of the object that is in motion.

In this example, the mass is found to be 50 kg using an accurate scale.

Next, determine the velocity of the 50kg object.

For this problem, the velocity is measured to be 10 m/s.

Finally, calculate the number of joules of energy using the formula above:

(K) = 1/2 *(m)*(v)^2

(K) = 1/2 *(50)*(10)^2

(K) = 25,000 Joules

## FAQ

**What is a joule?**

A joule is the SI unit for energy. Energy is a measure of the activity of a substance.

**What is kinetic energy?**

Kinetic energy is a type of energy that comes from the movement of objects.
