Solution
We can find out whether a body is moving with uniform or non-uniform motion by studying its distance-time graph.
A moving body which covers equal distances in equal interval of time, then the body is said to be moving with uniform motion, when a moving body covers unequal distances in equal interval of time, the body is said to be moving with non-uniform motion.
In graph I, the body covers 1 m in 1st second, 4 m in 2nd second, 4 m in 3rd second, 3 m in 4th second and so on...
In graph II, the body covers 0.5 m in 1st second, 0.5 m in 2nd second, 1.5 m in 3rd second, 1.5 m in 4th second and so on...
This implies P and Q both motions are non-uniform motion.
