Acceleration is the rate of change of velocity
Explanation:
What Acceleration Entails
The acceleration of an object is the rate  in which the velocity of the object is changing  with time, as it is moving or navigating a distance. Acceleration has both magnitude and direction, this makes it a vector quantity. An object at rest  has zero acceleration and  decelerating is used to describe a decrease in the acceleration of a body.
Acceleration can be can calculated using equation 1;
Acceleration = 1
Example of real-life acceleration application is when you speed a car as you travel. The car is said to be accelerating at this point.
