# Uniform Motion vs. Non-Uniform Motion — What's the Difference?

Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 31, 2023
Uniform Motion is when an object covers equal distances in equal intervals of time. Non-Uniform Motion is when an object covers unequal distances in equal intervals of time.

## Key Differences

Uniform Motion signifies an object's motion that remains consistent over time. This implies that the object travels equal distances in equal intervals, maintaining a steady velocity. Non-Uniform Motion, in contrast, means the object's movement is inconsistent, covering unequal distances in equal time spans.
In the context of Uniform Motion, it's simpler to predict an object's position at any given point in time because of its consistency. Non-Uniform Motion complicates this predictability, as the object’s velocity is not constant, making its future position less predictable.
When we discuss Uniform Motion, we often think of objects that move on a straight path without any external forces altering their velocities, such as a car on a straight road at a constant speed. On the other hand, when we talk about Non-Uniform Motion, the picture that comes to mind could be a car accelerating or decelerating due to various factors.
In scientific studies, Uniform Motion can be represented by a straight line on a distance-time graph, which is linear. Non-Uniform Motion is represented by a curved line, indicating variable distances covered over the same intervals of time.
Lastly, while Uniform Motion can be considered a special case of motion due to its constant velocity, Non-Uniform Motion is more common in the natural world. From speeding cars to the changing velocities of falling objects, Non-Uniform Motion embodies most of the movements we observe daily.
