Answer 2

Explanation:

A body is said to be in uniform motion if it covers equal distances in equal intervals of time, and to be in non-uniform motion, if it covers unequal distances in equal intervals of time.

If a body is revolving about a fixed point or axis, it is said to be circular motion.

i) A football player does not cover equal distances in equal time intervals, so its a non uniform motion.

ii) Fan rotates about the axis it is hanging with, so its a circular motion. It is also an example of uniform motion.

iii) Motion of an ant is non uniform motion.

iv) A town bus does not cover equal distances in equal time intervals, it is non uniform motion.

v) Moon revolves around the earth and covers equal distances in equal time intervals, it is uniform and circular motion.

vi) Motion of spectators in an auditorium is an example of non uniform motion.

vii) Motion of arms of clock is circular and uniform motion.
