Intro The Purpose of this activity was to see how you could drop an egg of the top of the bleachers without it breaking. The goal was to increase the time until impact therefore decreasing the force of impact. J=(F)(T) The goal was to have J= (F)(t) So the class designed egg cases to hld he egg. Since all the impulses were the same, if the time of impact was increased the force had to be decreased. |

My Case My egg case is a Card board box. The reason i choosed card board is because when it hits the ground, it increases the time of impact and decreases the force. Then inside of the box were two layers of bubble wrap. I wrapped it up to increase the time of impact so it would decrease the force of impact. My egg case will now have a big T and a little f . A increased time and a samll force so my egg would stay intact. The egg also had a thin case around it just so it would make a increase in time and a decrease in force. |

All of the egg cases should approximately have they same change in momentum because all the cases will be dropped at the same height and approximately have the same impact. They will all undergo the same change in velocity. All of the cases will have the same initial velocity and the same final velocity. They will also have the same mass. 1 pound.Since all of the egg cases have the same change in momentum they all have the same impulse exerted by the ground on the eggs. Term= impulse. The formula for this term is J=F^t. Impulse = (force)(elapsed time). |

Results My egg did not break. The reason my egg did not break is b/c my case had a long time until impact and since it was increased time until impact the force of impact decreased. My egg case was made of cardboard which helped because when the box hit the ground it compressed decreasing the force of impact. Also when my egg case hit the ground the two layers of bubble wrap decreased the force when the box hit the ground. They all had the same velocity and approximately the same weight so the only thing that mattered was the time of impact and the force of impact.

| Reflecting | I think if I had to design another experiment I would choose a bigger box and I would put the egg in a sock surrounded by packaging peanuts. Peanuts being the little white things so that the eggs force of impact would be decreases. This way the egg will not break. I would put the packaging peanuts in to increase the time of impact and to decrease the force of impact. |
| The real world | BBBoxers ride with punches so that they won't get hurt. Increasing the time of impact and decreasing the force of impact. When a person jumps on a trampoline they bend their knees when they land increasing time of impact and decreasing the force of impact. A helmet provides a increase until impact and a decrease in the force so you won't crack your head open. When you catch a baseball in a glove; the glove increases time of impact and decreases force. Tires decrease the impact of force exterted from the car and keep the car moving. If a person trips and falls they put their hads out increasing the time of impact therefor decreasing force. My shoes have shox in them increasing the time of impact of your foot and decreasing force of impact. If you wrap something in bubble wrap i ncreases for of impact and decreases the force of impact. The suspenion of a motorcycle increases time of impact and decreases force of impact when he lands a jump. when you jump on a pogo stick the spring goes up and down increasing time of impatt and decreasing force of impact. |
