Any change in motion (direction or speed) is a change in velocity.
Velocity is a vector quantity which means that it has a magnitude and a direction.
Uniform motion is when an object moves with a constant speed in a straight line. Uniform acceleration is when an object's velocity changes at a constant rate. In uniform acceleration, the speed of the object increases or decreases by the same amount over equal time intervals.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
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.
Newton's First Law of Motion (Law of Inertia) states that an object will remain at rest or in uniform motion unless acted upon by an external force.
The object will remain at rest if it was at rest or will maintain its motion with uniform velocity if it was moving.

uniform motion
The acceleration for uniform motion is zero. Uniform motion occurs when an object moves in a straight line at a constant speed, with no change in velocity over time. Since acceleration is the rate of change of velocity, any object experiencing uniform motion has an acceleration of zero.
Uniform motion: velocity doesn't change. Periodic motion: velocity changes all the time in a uniform, repeated way. This is most often seen inorbitring and the like, when the change of velocity is a change in direction (and also speed) and the object eventually returns to (roughly) the same place in space.
For an object moving with uniform motion, the equation of motion does not change. The equation remains the same as it describes the relationship between an object's position, velocity, and time regardless of whether the motion is uniform or non-uniform. Uniform motion implies constant velocity, so the acceleration term in the equation of motion is zero.
A body experiencing uniform motion does not have any acceleration. Acceleration is the rate of change of velocity, and since the velocity of a body in uniform motion remains constant, there is no change in velocity and therefore no acceleration.
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.
"Non-uniform" motion is "accelerated" motion.
Uniform velocity means constant speed and direction of motion. It is necessary for certain calculations in physics where a consistent rate of change is needed. In some cases, uniform velocity simplifies the analysis of motion as there are fewer variables to consider.
When a car's velocity is uniform, its acceleration is zero. This means that the car is not speeding up or slowing down, but maintaining a constant speed. Uniform velocity indicates that there is no net force acting on the car to change its motion.
if an object moves along a circular path, the only change in its velocity is due to the change in the direction of the motion. The motion of the object moving along the circular path is, which is a uniform circular motion, is therefore an accelerated motion:):):):/
