What is non-uniform motion? Give some examples.

When an object covers unequal distances in equal intervals of time, the object is said to be in non-uniform motion.
the motions that we see in our daily life are usually examples of non- uniform motion.

For example, if we drop a ball from the roof of a building, we will note that the ball covers 4.9 m in the 1st second, 14.7 m in the 2nd second, 24.5 m in the 3rd second, and so on.
Here, the ball covers increasingly larger distances in successive seconds as it falls down.
Thus, the motion of a freely falling body is non-uniform.

Examples of non-uniform motion are: 

(i) A stone dropped from the top of a building.

(ii) A ball thrown vertically upwards.

(iii) The motion of a train as it leaves the station.

(iv) The motion of a bus as it approaches a bus-stop.

(v) The motion of a ball rolling down an inclined plane.
