Velocity field

A velocity field is like a map that shows us how fast things are moving in different places. Just like how a map tells us where things are located, a velocity field tells us how fast things are moving. Imagine you are standing in a river and there are different currents all around you, some strong and some soft. The velocity field would show you how fast each current flows so you can plan where to swim. In science, we use this kind of map to study air and water flow, weather patterns, and even the movement of tiny particles like molecules!
