the speed of the stone is given by : v = u + g t so v = g t..
distance covered : s = u t +1/2 a t² = 1/2 g t²
Distance covered in time t to t+1 : 1/2 g [ (t+1)² - t² ]
= g (t +1/2)
The stone accelerates continuously till it reaches the ground.
It covers unequal distances in equal time periods. So NON Uniform motion. distance covered in each second: g/2 , 3g/2, 5g/2 ....
