What is meant by uniform motion ? Can you think of an example of a body in uniform motion?
If a body covers equal distances in equal intervals of time it is said to be in uniform motion.
For example, if a body in uniform motion covers 100 m in 50 s, then it must cover 10 m in every 5 s, 1.0 m in every 0.5 s, 0.1 m in every 0.05 s and so on.
