It depends on the velocity of the object at that time.

Explanation:

If the acceleration is negative, while the current velocity is positive (that is to say, the acceleration and velocity vectors point in opposite directions), what happens is the body slows to a brief halt, and then speeds up (accelerates) in the opposite direction.

This happens because the negative acceleration causes the object to decrease its speed at a constant rate. The speed will intuitively become #0# eventually, and after this moment the body will now move in the opposite direction as before.

If the acceleration is negative, while the current velocity is also negative (that is to say, the velocity and acceleration vectors point in the same direction), the body speeds up in that negative direction.
