Here's why:
* Acceleration is the rate of change of velocity. This means that an object is accelerating if its velocity is either increasing, decreasing, or changing direction.
* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
Examples:
* A car speeding up is accelerating because its velocity is increasing.
* A car slowing down is also accelerating because its velocity is decreasing.
* A car turning a corner is accelerating because its velocity is changing direction even if its speed remains constant.
