9th Physics | Motion | Uniform and Non-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
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.
A body is said to have non-uniform motion if it travels unequal distances in equal intervals of time
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.
