what is uniform and non uniform motion?

Uniform Motion:

A moving body that travels equal distances in equal time intervals is said to be in a state of uniform motion. The speed of the body is constant.

Non-Uniform Motion:

A moving body that travels unequal distances in equal time intervals is said to be in a state of non uniform motion. The speed of the body is not constant.

  • When an object moves in a straight line at constant speed, we say that it has uniform motion. The distance travelled by an object in uniform motion increases linearly. If you ride your bike at constant speed in a straight line, you cover distance steadily.

  • u can see uniform motion graph below!

s t graph of uniform motion

The distance-time graph is a straight line showing that the motion is uniform

  • When a body moves unequal distances in equal intervals of time or vice-versa, then the body is said to describe non-uniform motion. Examples a racing horse; merry-go-around; swing; automotive braking; throwing a softball; etc.

Examples of uniform motion : A car going along a straight level road at steady speed


An aircraft cruising at a level height and a steady speed 

A ship steaming on a straight course at steady speed 

A train going along the tracks at steady speed 

A cooling fan running at a fixed speed a space craft drifting between two galaxies; (very few real-life examples). 

Examples of non-uniform motion: a racing horse

; merry-go-around;

swing;

automotive braking

throwing a softball; etc.

UNIFORM MOTION ; IF THE BODY COVERS EQUAL DISTANCES  IN EQUAL INTERVALS OF TIME THEN THE MOTION IS UNIFORM .

NON-UNIFORM : IF THE BODY COVERS UNEQUAL DISTANCES IN EQUAL INTERVALS OF TIME THEN THE MOTION IS NON-UNIFORM .
