This is a bit of a tricky question! It's important to understand the difference between speed and velocity.

* Speed is how fast something is moving. It's a measure of how much distance is covered in a given time.

* Velocity is how fast something is moving *and* in what direction.

Here's how speed can remain constant while acceleration is happening:

Example: Imagine a car driving around a circular track at a constant speed of 60 mph. Even though the car's speed isn't changing, its velocity is constantly changing because its direction is always changing. This change in velocity means the car is accelerating.

Here's the key takeaway: Acceleration is a change in velocity, not just speed. If the direction of motion changes, even if the speed stays the same, there is still acceleration.
