# How to avoid an egg being cracked when dropped

• a129
In summary, the conversation suggests two solutions to avoid an egg from cracking when dropped onto a wooden block from the same height. The first suggestion is to drop the egg onto a cushion surface, which will absorb the momentum and increase the time of collision. The second suggestion is to drop the egg from the same height in outer space, where the lack of gravity will reduce the velocity and total impulsive force. However, this suggestion may need to be modified to an astronaut dropping the egg from the International Space Station, as there is no gravity to "drop" an object in outer space.

## Homework Statement

An egg is being dropped onto a wooden block. The egg cracks after an impact. The velocity of the egg just before the impact is 5m s^-1.

Give two suggestions and explain on how you would avoid the egg from cracking from the same height

Momentum:
F=ma,
F= m[(v-u)/t]
..= (mv-mu)/t

## The Attempt at a Solution

1. Drop the egg on a cushion surface. The cushion will absorb the momentum by increasing the time of collision

2. Drop the egg from the same height in outer space. The lack of gravity will reduce the velocity, thus reducing the total impulsive force. I'm confident in my first answer, but I'm not sure for the second one. Do you guys have any ideas or tips? Thanks for reading

You can't "drop" an egg where there is no gravity. If you hold it in your hand and let go, it will stay where it is. If you give it some intial velocity, it will keep on going.

Pretty creative!

Agreed, so answer #2 should be changed to an ISS astronaut dropping dropping the egg. @a129 -- why does that change the situation?

## 1. How can I prevent an egg from cracking when dropped?

To avoid an egg from cracking when dropped, you can try cushioning it with a soft material such as a towel or bubble wrap. You can also try placing the egg in a container filled with water to absorb the impact of the fall.

## 2. Does the height of the drop affect the chances of an egg cracking?

Yes, the higher the drop, the greater the force of impact on the egg. Therefore, dropping an egg from a lower height can decrease the chances of it cracking.

## 3. Can I prevent an egg from cracking by freezing it first?

No, freezing an egg will not prevent it from cracking when dropped. In fact, the frozen egg may be more likely to crack due to the increased weight and rigidity.

## 4. Is there a specific way to hold the egg to avoid it from cracking when dropped?

Yes, you should hold the egg with your fingertips at the top and bottom of the egg, rather than in the middle. This distributes the force of impact more evenly and can reduce the chances of cracking.

## 5. Are there any other methods to prevent an egg from cracking when dropped?

Another method is to wrap the egg in a sock or piece of fabric before dropping it. This can provide additional cushioning and absorb the impact of the fall. You can also try placing the egg in a container filled with rice or beans, which can act as a shock absorber.
