Uniform Motion:

Uniform motion refers to the motion of an object at a constant velocity or speed, where the distance traveled is directly proportional to the time elapsed.

Velocity:

Velocity is the rate of change of an object's position with respect to time, and is a vector quantity that includes both speed and direction.

Speed: Speed is the rate of change of an object's position with respect to time, and is a scalar quantity that only includes the magnitude of motion, not direction.
