* Constant Velocity: When a car moves with constant velocity, the speedometer needle will stay steady at a specific reading. This indicates that the car is traveling at a consistent speed in the same direction.
* Speeding Up (Accelerating): When the car speeds up, the speedometer needle will move upwards indicating that the car's speed is increasing. The faster the car accelerates, the quicker the needle will move.
* Slowing Down (Decelerating): When the car slows down, the speedometer needle will move downwards, indicating that the car's speed is decreasing. The more rapidly the car decelerates, the faster the needle will move downwards.
Important Note: The speedometer only shows the magnitude of the car's velocity (its speed). It does not indicate the direction of travel.
