This is a bit of a tricky question! It's true that you can have acceleration without a change in speed, but it's not the most common scenario. Let's break it down:

* Acceleration is the rate of change of *velocity*. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.

* Speed is just the magnitude of velocity, how fast an object is moving.

Here's how you can have acceleration without a change in speed:

1. Circular Motion:

* Imagine a car driving at a constant speed around a circular track. Even though the car's speed remains the same, its *direction* is constantly changing.

* This constant change in direction means the car's velocity is changing, and therefore it is experiencing acceleration. This is called centripetal acceleration and is directed towards the center of the circle.

2. Other changes in direction:

* Imagine a ball thrown straight up in the air. At the peak of its trajectory, for a brief moment, the ball's speed is zero. However, it is still accelerating downwards due to gravity.

In summary:

* Acceleration is about changes in *velocity*, which includes changes in both speed and direction.

* You can have acceleration without a change in speed if the direction of motion changes.
