* Speed: The object moves at a constant speed.
* Magnitude of Velocity: While the direction of velocity changes, its magnitude (speed) remains constant.
However, the quantity that does not remain constant is:
* Velocity: While the speed is constant, the direction of motion is constantly changing, causing the velocity vector to change continuously.
Think of it like this: imagine a car driving in a circle at a steady speed. Even though the car is moving at a constant speed, its direction is constantly changing, meaning its velocity is not constant.
