Question and Answer

A stone , when thrown on a glass window smashes the window pane to pieces , but a bullet from the gun passes through making a clean hole . Way ?

Answer

This is because velocity of bullet from the gun is very large . It takes very little time to cross the windown pane . Particles of window pane near the hole have to little time to share the motion of the bullet . Reverse is the case when stone is thrown with hand .
