Question
Why are porcelain objects wrapped in paper or straw before packing for transportation?
✓
Answer
Porcelain (or glass) objects are brittle in nature and can crack even small jerk on it. During transportation sudden jerks or even fall takes place.
When objects are packed in paper or straw etc.
The objects takes more time to stop or change velocity during jerks (due to breaks, or uneven road) so acceleration $\frac{(\text{v}-\text{u})}{\text{t}}$ decreased. So the force on objects will be smaller and objects become safer.
