when the body travels in unequal velocity in equal intervals of time.
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
Acceleration simply refers to the rate of change of a velocity. You might say that the effect of an acceleration - any acceleration - is therefore a change of velocity.
Force = Mass * Acceleration If you would multiply that by Mass, you would have mass^2 * acceleration. Which, to say the least, is nothing.
Their acceleration is zero.
Their acceleration is zero.
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
That simply means that the acceleration changes over time.
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.

uniform acceleration mean that the acceleration doesn't change over the course of time of the time considered for a certain
The answer depends on when "then" is.
Uniform acceleration means that the acceleration doesn't change over the course of time (of the time considered for a certain problem, at least).
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
Force = Mass * Acceleration If you would multiply that by Mass, you would have mass^2 * acceleration. Which, to say the least, is nothing.
