What Physics Principles Explain the Safe Drop of an Egg from a 5-Story Building?

AI Thread Summary
The discussion focuses on the physics principles involved in dropping an egg from a height, particularly the forces acting on the egg, such as gravity and air friction. Controlling these forces is crucial for preventing the egg from breaking, with suggestions to minimize initial velocity and maximize air resistance. The characteristics of protective materials and the effectiveness of layering them are also explored, emphasizing that a gradual impact can reduce the force experienced by the egg. An example project demonstrated that sand effectively cushioned the egg by dispersing the impact force. Overall, understanding these principles can help in designing effective protective measures for fragile objects during free fall.

I need to write a short paper on the physics of dropping an egg from a 5 story building. Below are questions I pondered...

What are the forces acting on the egg as it falls?

How can you control the forces that cause the egg to break?

What are the common characteristics of the materials that protected some eggs?

Does layering of materials play a role in protection?

As the egg falls, force of gravity, air friction and wind act on it. You can control the air friction by letting the egg drop from rest and not giving it an initial velocity.
 
thanks for your input... any other comments/suggestions?? IM DESPERATE!
 
Is it possible that an "egg" was chosen because of the (chicken) eggs aerodynamic shape, hence a study in aero/fluid dynamics, with respect to gravitational forces accelerating it, towards the earth.

It is the best 'airflow model' after all...
 
Its not the fall that hurts the egg; its the sudden stop.

Consider ways to increase the interval of impact. A slow change in momentum is associated with a smaller force.
 
I just did a project in class where we had to drop two eggs in a shoebox that also contained a brick. We had to cushion the egg anyway we wanted. The best cushion turned out to be sand. This worked best if you fixed it so the box broke open and the sand spilled out allowing the force of impact to be dispersed through the sand and the eggs were fine. It also helps to place the egg vertically with the small end facing down. We dropped these from the top of a football stadium.. I don't know if this helps any but hope so...
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
