a dictionary definition would be something like this: Uniform velocity, velocity in which the same number of units of space are described in each successive unit of time. Which is a constant speed - applies to both linear (straight line) or otherwise.

If an object moves with a constant speed along a straight line this is uniform velocity. It is also uniform if the object does not move. Athreal is wrong. Uniform velocity implies ONLY linear motion. Non-linear motion implies vector acceleration, which is incompatible with uniform velocity.

Well. If you travel with v = V in the direction (X,Y,Z) and there is no overall force on the particle that is travelling, then yes, this is uniform velocity. If, however, it is with constant speed on a curve or varying line, the velocity itself is changing. You may get something like v = (rsin t, rcos t, 0) and find speed is a constant of r (I'd have to work out the maths of it, but I am pretty sure this describes a circle of radius = r)

can an object have verifying velocity if its speed is constant? if yes give me example! thx
