Question
Does he velocity of falling rain drops continuously increases? Do all the drops of rains (big and small) reach the earth with the same velocity?
✓

Answer

Rain drops fall below the terminal velocity due to the viscosity of the air, hence their velocity does not increase continuously since the terminal velocity $V _t \propto r^2$, Hence, the big drop with reach will a more velocity than the small drops.
