Ask an Explainer
Q:
Why is faster than the speed of sound called supersonic?
A:
The word 'supersonic' comes from two words: 'super', meaning greater than, and 'sonic', which comes from the Latin 'sonus' and means 'sound'. Put them together and you get 'supersonic' or 'greater than sound'. Supersonic vehicles move faster than the speed of sound.
