- Speed is the rate at which an object changes its position, regardless of the direction of motion.
- Velocity, on the other hand, is the rate at which an object changes its position in a specific direction.
Speedometers measure the rate at which a vehicle is moving, but they do not take into account the direction of motion. This means that a speedometer can provide information about how fast a vehicle is traveling, but it cannot tell you which way it is headed. To determine the velocity of a vehicle, you would need to know both its speed and the direction in which it is moving.
