It is not only moving objects whose speed can vary. The speed of the wind and the speed of sound also vary. A typical value for the speed of sound in air is about 330 m/s.

Have you ever thought speed and velocity mean the same thing? Many people do. They often use these words as if they are alike. But in science, they are not the same. Speed tells us how fast something ...
