Hey there!
As we know that Acceleration is defined as the rate of change in velocity of a moving object.
▶Change in velocity/ time taken to make the change.
But when the velocity of the object decreases with time, the motion is said to be decelerated or to have negative acceleration.
Negative Acceleration is commonly referred to as #Retardation.
It is denoted by '-a'.
Hope this helps you dear ✌

Howdy!!!
your answer is -----
When a body move with some initial velocity and some time later its velocity decrease and its final velocity become zero , then for this situation acceleration become negative .
we also called it retardation .
MATHEMATICALLY --
let, initial velocity u and final velocity =0
therefore , from formula
a = v-u / t = 0-u/t
=> a = -u/t
hope it help you
