When will you say a body is in?
(i) Uniform acceleration?
(ii) Non - uniform acceleration?
(i) If a body travels in a straight line and its velocity changes by equal amounts in equal intervals of time, however small these time intervals may be, then the body is said to be in uniform acceleration.
(ii) When a body moves with a unequal velocity in equal interval of time, the body is said to be moving with non-uniform acceleration.
