Here's why:
* Acceleration is a change in velocity. Velocity has both speed and direction. So, acceleration can mean:
* Increasing speed: The object is going faster.
* Decreasing speed: The object is slowing down (this is deceleration).
* Changing direction: The object might be maintaining the same speed but altering its path.
Examples:
* A car speeding up is accelerating.
* A car slowing down is decelerating (a specific type of acceleration).
* A car turning a corner at a constant speed is also accelerating because its direction is changing.
In short, acceleration is a broader term that describes any change in velocity, including deceleration.
