* Velocity vs. Acceleration: Velocity describes how fast an object is moving and in what direction. Acceleration describes the rate of change of velocity.
* Constant Velocity: If car A is moving faster than car B, but both are traveling at a constant velocity, they both have an acceleration of 0.
* Different Acceleration: Car A could have a smaller acceleration than car B. Imagine car A is traveling at a very high speed and slowing down gradually (small negative acceleration). Car B could be traveling slower but accelerating quickly (larger positive acceleration).
To determine which car has greater acceleration, you need to know the rate at which their velocities are changing, not just their current velocities.
