Calculating the Speed of Real Objects

Here are a few ways to calculate the speed of real life everyday objects.

Speed: Example A

To calculate the average (mean) speed we need to use the total distance and the total time.

Speed: Example B

In this example you need to convert from m/s to mph. If you find this difficult then watch the video below to find out how you can do this.

Converting from mph to m/s

In GCSE Physics we should always try and use m/s, although in everyday life we often use miles per hour. This is how to convert from one to the other.
