An object moving at a constant speed means it is moving at a steady rate, without speeding up or slowing down. Here's a breakdown:

* Constant speed: The object covers the same distance in the same amount of time, regardless of the direction it's traveling.

* No acceleration: Since the speed isn't changing, the object isn't accelerating (acceleration is the rate of change of velocity).

Important Note: While an object moving at constant speed might not be accelerating, it could still be changing direction. This means it might be moving in a circle or curve, even though its speed remains the same.
