What is uniform motion?

Uniform motion describes an object that is moving in a specific direction at a constant speed. While uniform motion typically describes objects moving in a straight line, uniform circular motion consists of an object moving in a perfect circle at a constant speed.

Uniform motion describes a small set of circumstances because, in real life, most movement is not observed at a constant speed or direction. When an object travels in a straight line in uniform motion, the distance it has traveled can be calculated by multiplying the velocity by the time it took to travel the distance. Any object that moves with deviations in its speed or direction is said to be undergoing non-uniform motion.
