Question

explain with different example to show when a body said to have (i) uniform motion and (ii) non uniform motion

Answer 1

when a body covers equal distance in equal interval of time then it is said to be in uniform motion
for example - when a car covers 60 km in every 1 hour then it is said to be in uniform motion
when a body covers unequal distance in equal interval of time then it is said to be in non uniform motion
for example - when a car covers 50 km in 1 hours and 90 km in the second hour
.....
hope it helps

Answer 2

Uniform motion= an object is said to possess uniform motion if it travel equal distance in given equal interval of time non uniform = an object is said to possess non uniform motion if it cover unequal distance in equal interval of time
