GCSE Physics

Speed, Distance & Time

In everyday life we use speeds like miles per hour (mph), whereas in this race we would use metres per second (m/s). It is the latter which we tend to use in Physics.

The equation for speed can be remembered from the unit itself: m/s - m is metres (distance), s is seconds (time). It can, of course, be rearranged to give:

We write this in symbol form as d = s t
