Egg Drop

I did the egg drop with Sarah Pascual and the both of us had trouble at first with thinking of ideas for our egg drop device. We eventually agreed on surrounding the egg with light sponges, then bubble wrap, and finally placed in a bag filled with shredded news paper and plastic bags. All of our wrappings were used in order to decrease the amount of force exerted on the egg when it was dropped. Since all of our materials were light our device had a low terminal velocity or highest speed. A lower terminal velocity is good because it in turn means a smaller impulse or change in momentum. During the impact with the ground our device has weight force going down due to the pull of the Earth's gravity and normal foce going up due to the Earth pushing up with equal and opposite force to gravity. Our outside trappings might have been a bit too extensive and added unnecessary weight to our device. I think lighter would have been better and if we did it again I would look to make the device as light as possible. I think the light sponges and the bubble wrap might have been enough just by themselves to protect the egg, but if we did it again I would might want to just use more soft sponges and bubble wrap because they're light and provide great protection.

This is a force diagrams that shows the forces acting upon my egg drop device as it hits the ground. Also this is a cross section drawing of my device showing all of the materials used.
