Define acceleration. State a relationship connecting $u, v, a$ and $t$ for an accelerated motion. Give an example of a motion in which acceleration is uniform.

(N/A) Acceleration is defined as the rate of change of velocity of an object with respect to time. Mathematically,it is expressed as $a = (v - u) / t$.
The relationship connecting initial velocity $(u)$,final velocity $(v)$,acceleration $(a)$,and time $(t)$ is given by the first equation of motion: $v = u + at$.
An example of motion with uniform acceleration is the motion of a freely falling body under the influence of gravity.
