Final answer:
The speedometer of a car measures speed and not velocity. Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
Step-by-step explanation:
The speedometer of a car measures speed and not velocity. Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. The speedometer of a car measures speed and not velocity.
Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction. The speedometer displays the instantaneuos speed of the car, but it does not indicate the direction of the motion.
