In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.

Although these stories share similarities in the plot, the characters, and the theme they also show many differences.

In one case, Archimedes took the basic pulley and created a bigger compound system with additional non-stationary pulleys which allowed a person to lift great weights with only a fraction of the effort. Historically, he used a crane-like construction which used the compound pulley system to lift large Roman ships out of the sea, and drop them back down, causing them to break

Medieval weapons just started as spears but the medieval era evolved quickly they invented the catapult, swords, cannons, crossbows.

Our 2nd and 3rd trials which had 1 and 2 paperclips caused our time to decrease to 1.6 and 1.8 seconds. Our last trial with the most mass of 3 paper clips lasted the shortest amount of time, only 1.43 seconds. Our responding variable was the time flown and the controlled variable was who threw the airplane
