(N/A) $(i)$ $A$ body is said to be in uniform acceleration if it travels in a straight line and its velocity increases or decreases by equal amounts in equal intervals of time.
$(ii)$ $A$ body is said to be in nonuniform acceleration if the rate of change of its velocity is not constant,meaning its velocity changes by unequal amounts in equal intervals of time.
