tion is vector quntity
Acceleration is a change in velocity. Velocity is defined as the speed of an object in a specific direction. It is a vector quantity. Thus acceleration could be a rate of change of speed, velocity or both. In addition, acceration can be negative. In physics terms, there is no such thing as "Deceleration". Any change is considered to be acceleration.

Could be time for a tune up.
acceration = velocity X time
Not until it passes the North Pole.
Acceleration is the rate of change of velocity over time, where an object is speeding up. Retardation, also known as deceleration, is the rate at which an object slows down or decreases in velocity over time.
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
90 degrees
The acceration is 0, because the velocity is constant.
That means acceleration towards the center. For example, this happens any time something moves in a circle.
