What is the example where acceleration is either uniform or non uniform?
If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
What is a speed graph?
a speed graph shows us how the speed of a moving object changes with time
What is the nature of velocity time graph of a body moving with uniform retardation?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
What is the nature of the distance-timegraphs for uniform and non-uniform motion of an object?
-- The distance/time graph for an object in uniform motion is a straight line,which may be sloped.-- The distance/time graph for an object in non-uniform motion may be a linethat isn't straight. But even if the graph is a straight line, that's not enoughto guarantee that the object's motion is uniform ... the distance/time graphreveals the object's speed, but not the direction of its motion.
What is non uniform speed?
One that changes. For example: you driving a car in a city.

What would be the shape of a speed - time graph of a body?
If speed changes, then the speed/time graph has up/down curves in it.
What is a speed graph?
a speed graph shows us how the speed of a moving object changes with time
How would you describe the slope of a graph showing changing speed?
The angle of the graphed slope changes with changes in speed.
What is the nature of velocity time graph of a body moving with uniform retardation?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
Ununiform speed means what?
The term normally used is not "ununiform", but "non-uniform". That simply means that speed is NOT uniform - in other words, it changes over time.
What part of the graph represents uniform positive and negative acceleration Calculate this acceleration.?
The answer depends on whether the graph is that of speed v time or distance v time.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
What is the nature of the distance-timegraphs for uniform and non-uniform motion of an object?
-- The distance/time graph for an object in uniform motion is a straight line,which may be sloped.-- The distance/time graph for an object in non-uniform motion may be a linethat isn't straight. But even if the graph is a straight line, that's not enoughto guarantee that the object's motion is uniform ... the distance/time graphreveals the object's speed, but not the direction of its motion.

2 differences between uniform and non uniform motion?
if the field strength of induction is same at every point in both magnitude and direction is called uniform magnetic field. in uniform magnetic field the lines of force are straghit parallel and equidistant.
