⭐Acceleration⤵
Acceleration of a body is defined as the rate of change of velocity. Acceleration has both magnitude and direction, hence it is a vector quantity.
⭐Angular Acceleration⤵
The rate of change of angular velocity is called angular acceleration.
⭐Centripetal Acceleration⤵
If a body is moving along the circumference of a circle, then the acceleration produced is directed towards the centre of the circle. This acceleration is centripetal acceleration. Force due to centripetal acceleration, acting towards the centre, is called the centripetal force.
⭐Retardation⤵
When the final speed of a body is less than its initial speed, the body is said to be retarding. Retardation can also be expressed as acceleration with a minus sign.
⭐Uniform Acceleration⤵
If velocity increases by equal amounts in equal intervals of time in a straight line, however small the intervals of time may be, the body is said to be have in uniform acceleration.
Hope it helps☑

hey mate ,
here is your answer :)
"""""""""""""""""""""""""""""""""""""""""
acceleration:- Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity
angular acceleration:- The rate of change of angular velocity with respect to time. Angular acceleration is measured in revolutions per minute squared or in radians per second squared
Centripetal Acceleration. Centripetal acceleration is the rate of change of tangential velocity
retardation.:-Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative.
uniform acceleration:-.uniform acceleration motion in motion in which the body moves with the same time and distance
