Question

How are glass items packed for transportation using a bubble wrap or hay protected from damage?

Answer 1

When a packed box experiences a jerk or a collision during transport, the glass items inside come to rest over a longer time due to cushioning materials like bubble wrap or hay. This increases the time taken for their velocity to reduce to zero.

As the time of impact increases, the rate of change of velocity (acceleration) decreases. According to Newton’s Second Law of Motion (F = ma), a smaller acceleration results in a smaller force acting on the glass items, thereby preventing them from breaking.
