* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. A negative velocity indicates motion in the negative direction.
* Acceleration is the rate of change of velocity. Positive acceleration means the velocity is increasing in the positive direction.
Imagine a car moving backwards (negative velocity). If you apply the brakes (positive acceleration), the car will slow down.
Here's a more detailed explanation:
* Initial state: The object is moving in the negative direction (e.g., to the left).
* Acceleration: The positive acceleration is acting in the opposite direction to the velocity.
* Result: The acceleration causes the object to slow down, meaning its speed decreases. However, it will still be moving in the negative direction until the velocity reaches zero. After that, it will start moving in the positive direction (e.g., to the right).
In essence, positive acceleration acts to oppose the negative velocity, causing the object to slow down.
