Acceleration is defined as the rate of the change in the velocity. The S.I. unit of the acceleration is ms⁻². 

The Dimension of the acceleration is [a] = LT⁻¹/T

  = LT⁻² 

Acceleration is the vector quantity. It means that it has both the magnitudes and direction. 

The Formula to calculate the acceleration is ⇒
    a =  \frac{v - u}{t}
where, a is the acceleration, v is the final velocity and u is the initial velocity. 

The acceleration is of two types, 
1. Uniform Acceleration ⇒ In uniform acceleration the rate of the change of the velocity is uniform with respect to the time. 

2. Non uniform Acceleration ⇒ In non-uniform acceleration, the rate of the change in the velocity is not uniform, i.e. it is variable with respect to the time. 


Hope it helps.

HEY!!

____________________________

⏩Acceleration means the change in the velocity per unit time.

⏩A body is said to be accelerated if its velocity is increased or decreased.

⏩Acceleration only takes place if the velocity changes.

⏩If the velocity of the body increases with time, then body is positively accelerated.
