* Speed is a scalar quantity: It only tells us how fast an object is moving, regardless of its direction.
* Velocity is a vector quantity: It tells us both the speed and direction of an object's motion.
Example: Imagine a car traveling around a circular track at a constant speed of 50 mph.
* Speed: The car's speed is constant at 50 mph.
* Velocity: Even though the car's speed is constant, its velocity is constantly changing. This is because the car's direction of motion is changing as it moves in a circle.
Key Point: For velocity to be constant, both the speed and direction must remain the same.
