KidzSearch Safe Wikipedia for Kids.

**Distance** is how far one thing is from another thing. Distance is a measure of the space between two things.

## Examples of Distance

- One ball is 5 feet from another ball. The distance between the two balls is 5 feet.
- John walks north at 6 kilometres per hour for one hour. John walks a distance of 6 kilometres.
- A circle is a curved line. Each point on the circle is the same distance from the centre of the circle.

## Displacement

Distance is different from displacement. Displacement is the difference between a starting point and a finishing point.

## Example of Displacement

A and B are 1 metre apart. Tom walks from A to B. Then Tom walks from B back to A. The distance Tom walked is 2 metres. Tom's displacement is 0 metres, because Tom started at A and finished at A.
