**Weight** is the **force** acting on an object due to **gravity**. The **weight** of an object is defined as the force of **gravity** on the object and can be calculated as the **mass** times the **acceleration **due to **gravity**.

## Demo

In this tutorial you will learn how to calculate the **weight** of an object on the moon due to its force of **gravity**.

The equation is written like this:

${ \textit W} = {\text m \;} {\text x \;} {\text g}$
