A project involves creating a device to protect an egg from an 11-meter fall, inspired by bike helmet design. The device has been tested successfully, and the next step is to explain the physics principles behind its effectiveness. Key concepts to discuss include energy conservation, momentum conservation, pressure, air resistance, and terminal velocity, all of which contribute to reducing impact forces. The forum encourages sharing explanations and questions for further assistance. Understanding these principles is essential for articulating why the design works.

well I am doing a project in my physics class where i have to create a device for an egg to survive a 11m fall. i created a device similar to that of a bike helmet.
its been tested and it works but now i have to discuss the reason why it works. i need to include physics principles and the formulas for them such as energy conservation, momentum conservation, pressure, air resistance, terminal velocity etc. etc. and how they help prevent an egg from breaking. anything will help. thanks

It's your project. Talk to us...
 
we can't help you with your project completely,

instead you try some explanations for the same ... and ask us if they are correct or any of your queries here!
we'll be happy to help then!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
