When will you say a body is in (i) unifrom acceleration ? (ii) non-uniform acceleration ?

Explanation

(i) A body is said to be in uniform acceleration, when velocity of the body changes by equal amounts in equal intervals of time. For example, motion of a body falling under gravity.
(ii) A body is said to be in non-uniform acceleration, when velocity of the body changes by unequal amounts in equal intervals of time. for example, motion of a car on a highway through city limits.
