Here's why:
* Acceleration is the rate of change of velocity. This means acceleration occurs when:
* Speed changes (object speeds up or slows down)
* Direction changes (object turns)
* Constant velocity means the object is moving at a steady speed in a straight line. Since there's no change in speed or direction, there's no acceleration.
Example:
Imagine a car driving down a perfectly straight highway at a constant 60 mph. The car is moving, but it's not accelerating because its speed and direction are not changing.
