An object of constant **mass** accelerates in proportion to the **force** applied.

## Demo

In this tutorial you will learn how to calculate the **force** applied to an object if you are given its **mass** and **acceleration**.

The equation for this calculation is written like this:

$F = { \text m\; \text x \; \text a}$

## Chilled practice question

Calculate the **force** applied to cannon ball which **accelerates** at 7**m/s ^{2}** which has a

**mass**of 5

**Kg**.

## Frozen practice question

A rocket has a driving **force** of 15 **N** and a mass of 250 **g**. Calculate the **acceleration** of the rocket.

## Science in context

**Force** (N) = **mass** (kg) × **acceleration** (m/s²). Therefore, an object of constant **mass** accelerates in proportion to the **force** applied.
