* Velocity is speed with a direction.

* Speed is how fast something is moving.

Therefore, a change in velocity without a change in speed would be a change in direction.

Here are some examples:

* An object moving in a circle at a constant speed: The object's speed remains the same, but its direction is constantly changing, so its velocity is changing.

* A car turning a corner at a constant speed: The car's speed might be the same, but its direction changes, meaning its velocity changes.
