What is uniform motion?

Uniform motion means moving at a constant speed in a straight line. The object covers equal distances in equal amounts of time, with no change in direction or pace. This is modeled by a straight-line distance-time graph and implies zero acceleration.

Example: A train traveling at 60 km/h on a straight track exhibits uniform motion.

This basic concept is a cornerstone for understanding more advanced topics such as acceleration and non-uniform (variable) motion.
