Question

when will you say a body is in (a) uniform acceleration ? (b) non uniform acceleration?

Answer 1

when speed of body increase in uniform rate it is uniform acceleration otherwise if increasing at noon uniform rate it is non uniform acceleration

Answer 2

(i) A body has a uniform acceleration if its velocity changes by equal amounts in equal intervals of time. The motion of a freely falling body is an example of uniform acceleration.

(ii) A body has non uniform acceleration if its velocity changes by unequal amounts in equal intervals of time. the motion of a car on a crowded city road is an example of non uniform acceleration.
