Acceleration is a vector quantity because it has both magnitude and direction. When an object has a positive acceleration, the acceleration occurs in the same direction as the movement of the object. When an object has a negative acceleration (it's slowing down), the acceleration occurs in the opposite direction as the movement of the object. read more
Acceleration is a vector quantity that is defined as the rate of change of velocity. If an object is said to be accelerating then it increases its velocity.we know that velocity is a vector quantity, thus acceleration is also a vector quantity. read more
Acceleration is a vector quantity and not a scalar, because it has both magnitude and direction. Since the definition of acceleration is “rate of change of velocity” or “change in velocity in a single unit of time”, it means velocity is always involved which is already a vector quantity. read more
