**Weight** is the **force** acting on an object due to **gravity**. The **weight** of an object can be defined as the **force** of **gravity **on the object. Since the **weight** is a force, its unit is the **Newton**.

## Demo

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

The equation is written like this:

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

## Chilled practice question

Calculate the **weight** of a bench on Earth which has a **mass** of 25 **Kg**.

## Frozen practice question

Calculate the **mass** of an elephant if it has a weight of 60 **KN** on Earth.

## Science in context

Weight is the force acting on an object due to gravity.
