# Uniform Acceleration - Fridge Physics

Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.

## Demo

In this tutorial you will learn how to calculate uniform acceleration.

The equation is written like this:

${ \text v^{2} \; \text – \; \text u^{2} \; \text = \; \text 2as}$

## Chilled practice question

A racing car travelling at 20 m/s decelerates uniformly at 1.5 m/s2 towards a slip road 100 m away. Calculate its velocity when it reaches the slip road.

## Frozen practice question

A ball is dropped 12 m from the top of a building. Calculate the velocity of the ball when it hits the ground. Ignore any value for air resistance. Acceleration due to gravity is 9.8m/s2

## Science in context

Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period.
