When the velocity changes. And the velocity will change when the forces on an object change. For instance, some types of friction forces change as a function of velocity.
I assume you mean "non-uniform". "Uniform" simply means that the velocity (in this case) doesn't change.
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
The average velocity of a body with non-uniform acceleration can be calculated by taking the average of the initial and final velocities over the time interval. This is done by adding the initial and final velocities and dividing by 2. Mathematically, the formula for average velocity is (v_initial + v_final) / 2.
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
The formula for non-uniform motion is given by: [ v_f = v_i + at ] where ( v_f ) is the final velocity, ( v_i ) is the initial velocity, ( a ) is the acceleration, and ( t ) is the time taken.

Non uniform velocity is known as variable velocity.

That simply means that its velocity is changing.
That means that something moves in a circle, but that the velocity is not uniform.
In uniform motion, the velocity of the object is constant: both in magnitude and in direction. In non-uniform one or other (or both) of these will vary.
The formula for non-uniform motion is given by: [ v_f = v_i + at ] where ( v_f ) is the final velocity, ( v_i ) is the initial velocity, ( a ) is the acceleration, and ( t ) is the time taken.
No, an object cannot maintain uniform velocity when its acceleration is non zero. If an object is accelerating, its velocity will be changing over time, so it cannot maintain a constant velocity. Uniform velocity means the speed and direction of the object remains constant.
Non-uniform motion refers to an object moving at varying speeds and/or changing direction during its motion. This means that the object's velocity is not constant, unlike uniform motion where the velocity remains the same throughout.
Uniform velocity refers to a situation where an object travels in a straight line at a constant speed without changing its direction. This means that the object covers equal distances in equal intervals of time.
