* Speed remains constant: Speed is a scalar quantity, meaning it only has magnitude (how fast something is moving). If the car maintains the same speed, its speed stays the same even while turning.
* Velocity changes: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Since the car changes direction while turning, its velocity changes even if the speed stays the same.
Think of it this way:
* Speed: Like how fast you are running on a treadmill.
* Velocity: Like the path you are taking on a map.
Example:
Imagine a car driving at a constant speed of 60 mph down a straight road. Then, it turns onto a circular road and continues at 60 mph.
* Speed: Remains at 60 mph.
* Velocity: Changes because the car's direction is changing constantly.
Key Point: While the car's speed may be constant, its velocity is constantly changing because its direction is changing. This is why we say a car turning at constant speed is accelerating, even though its speed isn't increasing.
