A car has an acceleration of 2 m/s2, what does this tell you about the velocity of the car . Explain what is meant by an acceleration of -2 m/s2.

In the first part, the car increases its velocity by 2 every second;thus after 2 seconds it will be moving at 4m/s^2, 6,8,10...etc. If it has a negative acceleration, it's slowing down.

The acceleration of a car tells us how quickly its velocity is changing. In this case, if a car has an acceleration of 2 m/s^2, it means that its velocity is increasing by 2 meters per second every second. The positive sign indicates that the velocity is increasing in the positive direction.

On the other hand, an acceleration of -2 m/s^2 means that the car's velocity is decreasing by 2 meters per second every second. The negative sign indicates that the velocity is decreasing in the negative direction. In other words, the car is slowing down.

To calculate the change in velocity, we can multiply the acceleration by the time for which it is applied. For example, if the car accelerates at 2 m/s^2 for 5 seconds, the change in velocity would be 2 m/s^2 * 5 s = 10 m/s.

well i don't really know how to explain the first part sorry.. but a negative acceleration for a car means the car is stopping.
