Want this question answered?
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
This would indicate negative acceleration, which would mean that the object in question is speeding up.
slowing down
Retardation or negative acceleration or deceleration.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.

AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
No. A negative acceleration could mean a change in direction
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.
Negative acceleration, also known as deceleration.
