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 velocity time graph for uniform retardation?
straight line curve
Why does velocity stay constant with decreasing momentum?
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.
What determines the nature of the path followed by the particle?
Velocity
What could be the nature of the path of a moving body if its velocity and acceleration be always directed along the path?
It will move faster and still faster along the path. However, it will require an infinite force accelerating it and since such a force cannot exist, there is no possibility of such an event happening.
Why is force necessary in order to accelerate?
An object's nature is to adhere to it's current state (by state I mean velocity). With no force applied, nothing will cause it to change its velocity.

What are the nature of the distance time graphs for uniform and non unifrm motion of an object?
A distance-time graph for an object moving at a constant velocity will be a straight line - the gradient of the line corresponds to the velocity. Non-uniform motion will cause the gradient of the line to change.
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.

Sentences with word uniform?
every school has its Uniform. The fact is very uniform in nature.
What does the medical term homogeneous mean?
Uniform in structure, composition, or nature; the opposite of heterogeneous.
What is the nature of graph between kinetic energy and mass when velocity is constant?
The graph is linear.
Are black fleece caps authorized?
With the old BDU uniform, yes. Not anymore with the adoption of the ACU uniform, however. The purpose of the camoflage pattern used by the ACU uniform was, in part, to eliminate the color black completely from the uniform, as nothing found in nature is actually black.
