Average Mass Of Egg Experiment

Prior to designing a contraption to hold the grade A egg, a series of tests were conducted in order to accurately design a contraption that would uphold under the force of the fall without the egg cracking or popping out. The first test was to determine the average mass and dimensions of the eggs. The materials needed to conduct this section of the lab include 60 eggs, a scale, a string, and a caliper. In order to obtain the mass, an egg was placed on a scale and the mass was recorded; this was repeated for the other 59 eggs. After they were all weighed the average mass was recorded by adding up all 60 masses and dividing by 60, this measurement was then recorded. Secondly, the string was wrapped around the minor and major circumferences
Before running the test, all of the materials had to be gathered: pvc pipe, ring stand, labquest, photogate, eggs, force probe, and plates. The testing apparatus was set up next by placing one photogate on the ground attached to a ring stand and connected to a labquest. Vertically above the photogate, a 2 meter PVC pipe was held in line with the photogate. A paper plate was placed under the PVC pipe and directly above a force probe, which itself was connected to a labquest. The collection button was pressed and then an egg was dropped through the pipe, one at a time. After the eggs broke, the final velocity and force were recorded. This process was repeated for 29 more eggs. Subsequently to testing, the momentum was calculated by using the equation
At the height of the 2 meters, the carrier has no kinetic energy and once it is dropped, potential energy is converted into kinetic energy.1 That does nothing to help explain why the kinetic energy was higher, it should technically not exceed the potential energy given. A limitation to this could be a calculation error that ultimately skewed the rest of the data. Other limitations to this experiment could be that each time the carrier is tested the tape, string, or ways to hold the contraption together, lost its adhesive or grip. Items become unstuck when the surfaces are pulled apart and air intervenes between the adhesive and the surface, breaking the bonds between the molecules.2 Since the carrier was tested outside of class several times prior to the final test, this could contribute to why the product failed. Prototype #3 should have been recreated with fresh tape for the final. Another contributing factor to slightly off data would be that not all 30 eggs were able to get a reading on the starting tests. Simply, the data would have become more accurate as more trials were conducted. There were technically difficulties getting both labquests on the right setting and working at the same
