Vedclass · Answer

(C) Glass or chinaware items are fragile and prone to breaking upon impact. When these items are packed with straw,the straw acts as a cushion. According to Newton's Second Law of Motion,the force exerted is inversely proportional to the time taken for the change in momentum $(F = \Delta p / \Delta t)$. By using straw,the time taken for the change in momentum is increased during any sudden jerk or collision. As a result,the force exerted on the glass or chinaware is significantly reduced,preventing breakage.
