9th Physics | Motion | Uniform and Non-uniform Motion

UNIFORM MOTION

A body is said to have uniform motion if it travels equal distances in equal intervals of time, howsoever small the time interval may be

For example

This body is travelling 25 m in the first second, 25 m in the second and 25 m in the third second. It is therefore undergoing uniform motion.

NON-UNIFORM MOTION

A body is said to have non-uniform motion if it travels unequal distances in equal intervals of time

For example

If a body starts at A and acted upon by a force it initially travels slowly then it gains speed. It travels 5 m in the first second, 15 m in the second and 25 m in the third. As these are unequal distances, it is known as non-Uniform motion.
