Here's how I interpret it.


To me,

  • constant means that the variable remains totally unchanged throughout

  • uniform means that the variable is unvarying throughout

A lot of the time, you can use these two terms interchangeably. If I had to pick out certain instances where one is preferred, then here are some:

If a car is moving with a velocity of #30# #"m/s"# and this velocity does not change (magnitude or direction) throughout the motion, the velocity is constant.

On the other hand, if a car is traveling with a speed of #30# #"m/s"# in a circular path, and the speed does not change but its direction is changing constantly, the motion is uniform (it does not vary, as it goes through the same motion over and over).
