The real dilemma is = how do we define Uniform motion.
Is motion a wave? Do wave move Uniformly? When a mass fall toward the earth due to the power of gravity that caused to move , does it fall uniformly with uniform acceleration?
The answer is no.The reason is the Gravity field is not constant during the free fall of the mass.
We are not able to measured instantaneous velocities whether it inertial motion or non inertial motion . We can only measure averages.
So we calculate velocities on the basis of acceleration ,the value of acceleration is only an average.
Formula to estimate the average velocity is as follows;
V= a x t
where v =is velocity ,a= is average acceleration and t= is the time at the instance that the mass has moved.
The average acceleration is then considered constant and therefore uniform.
However in reality Uniform motion in terms of uniform velocity and and acceleration does not exist in the reality of the Universe.
The proof of this stems from the fact that J. Keppler was able to postulate that the orbital motion of the Earth was not Uniform but continually changing with time forming an elipse rather than a circle.

With uniform motion,

s = vt
where s = distance
v = velocity
t = time

With acceleration,

s = vot + 0.5at^2

where vo = initial velocity.
