Joule Calculator

Formula

The formula to calculate the Kinetic Energy (K) is:

\[ K = \frac{1}{2} m v^2 \]

Where:

\( K \) is the Kinetic Energy (Joules)
\( m \) is the Mass (kg)
\( v \) is the Velocity (m/s)

What is a Joule?

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

Example Calculation

Let's assume the following values:

Mass (m) = 10 kg
Velocity (v) = 5 m/s

Using the formula to calculate the Kinetic Energy:

\[ K = \frac{1}{2} \cdot 10 \cdot 5^2 = 125 \text{ Joules} \]

The Kinetic Energy is 125 Joules.
