You're absolutely right! Here's why the acceleration of an object moving at a constant velocity is always 0:

Acceleration is the rate of change of velocity. This means:

* If velocity is constant (not changing), then the rate of change is zero.

* Zero rate of change means zero acceleration.

Think of it like this:

* Constant velocity: Imagine driving a car at a steady 60 mph. Your speed isn't increasing or decreasing.

* No acceleration: Since your speed isn't changing, you aren't accelerating.

Key Point: Acceleration only occurs when the velocity of an object changes, either in speed or direction.
