# Distance

## Contents

## Key Stage 1

### Meaning

**Distance** is how far away something is.

### About Distance

Distance is usually measured with a ruler. Distance can also tell us the length, width or height of something. There are different units of distance you should know:

- Kilometres: For the distance between towns that are far away.
- Metres: For the length of a room.
- Centimetres: For the height of a table.
- Millimetres: For the width of a pencil.

### Examples

- Birmingham is 160 kilometres away from London.
- My classroom is 12 metres in length.
- My table is 120 centimetres high.
- My pencil is 9 millimetres wide.

### Used in a Sentence

- The
**distance**between London and Birmingham is 160 kilometres. - The front of my classroom is a
**distance**of 12 metres from the back of my classroom. - The
**distance**between the floor and the top of my table is 120 centimetres. - One side of my pencil is a
**distance**of 9 millimetres from the other side of my pencil.

## Key Stage 2

### Meaning

Distance is how far something has travelled usually measured in metres.

## Key Stage 3

### Meaning

Distance is a measure of how far something has travelled measured in metres.

### About Distance

- Distances may also be referred to as lengths.
- Width, height and depth are a type of distance between the edges of an object.

There are several common units of distance:

- Miles - A non-scientific unit of distance.
- Kilometres - The distance between towns.
- Metres - The height of a building.
- Centimetres - The width of a doorway.
- Millimetres - The length of an insect.
- Micrometres - The length of a cell.

## Key Stage 4

### Meaning

Distance is a scalar quantity representing the total length of a path between two points.

### About Distance

- Distance is a scalar because it has magnitude but not direction.
- The SI Unit of distance is the metre.
- Distances may also be referred to as lengths.
- Width, height and depth are a type of distance between the edges or sides of an object.
- Distance travelled is used, along with time, to calculate the speed of an object.
