* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Speed is a scalar quantity, meaning it only has magnitude.
Therefore, a car can move at a constant speed (magnitude) while changing direction, which would result in a changing velocity.
Example:
Imagine a car driving around a circular track at a constant speed of 50 mph. Even though the speed is constant, the car's velocity is constantly changing because its direction is changing.
In summary:
* Constant speed means the car is covering distance at a steady rate.
* Changing velocity means the car's direction is changing, even if its speed is constant.
