Uniform velocity is velocity unaffected by acceleration. Variable velocity is velocity affected by acceleration.
Lauren "Physics above all!"
I assume you mean "non-uniform". "Uniform" simply means that the velocity (in this case) doesn't change.
Uniform acceleration simply means that the acceleration doesn't change over time. Variable acceleration may change over time. For practical purposes, problems with uniform acceleration (such as the one provided by gravity, near the Earth's surface) are much easier to calculate. Variable acceleration requires integration, which isn't taught in high school, but may appear at college if you study in a career in engineering.
Uniform velocity means that an object is moving in a straight line at a constant speed, while constant velocity adds the additional condition of moving with a constant speed and direction. In other words, constant velocity implies both uniform speed and no change in direction.
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.
linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.
Non uniform velocity is known as variable velocity.

The condition in which a body moving with uniform speed has a variable velocity is when the direction of motion changes even though the speed remains constant. This means that the object is accelerating, even though its speed does not change.
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.
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
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.
