When an acceleration value is positive, thisdoes not necessarily mean that the object is speeding up. A positive acceleration can indicateeither that the velocity of the object is increasing in a positive direction or decreasing in anegative direction. Alternatively, if the acceleration is negative, velocity can either beincreasing in a negative direction or decreasing in a positive direction.
