Hint: A motion is defined as the change in the position of any object. To answer the above question, we should have the basic knowledge of what motion is and what are the types of motion. When we talk about motion of any body, then there are two types by which a body can be in motion the first is uniform motion and the second is Non-Uniform motion.

Complete answer:
A motion in which the body does not accelerate or a body does not change its speed is called Uniform Motion and when a body changes its speed with respect to time then it is said to be accelerated or de accelerated and this type of motion is called non uniform motion.
In Linear motion the body travels in a straight line while in circular motion the body travels in a circular path. So, in Uniform linear motion the body travels with a constant speed in a straight line and does not change its direction while in motion, for example: A car moving on a straight road with a constant speed is an example of uniform linear motion.
While in Uniform Circular Motion the body travels with a constant speed but its direction changes with respect to time or even we can say that the direction of the body will be different at every instant of time, for example: Earth Revolving around the sun with a constant speed but its direction changes with time is a perfect example of uniform circular motion

Note:
There is a difference in between speed and velocity, if we talk about speed then this means we are not taking direction with it like in a circular motion speed can be constant but the object changes its direction and hence we can not say that the velocity is also constant but for a car moving on a straight line or road we can say that both speed and velocity are constant because it does not changes its speed.
