Egg Drop Essay
The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history, engineering, and mathematics and physics. To fully understand how an egg drops, the knowledge of the history of physics, the engineering behind a device, and the mathematics and physics of free-fall is needed.
Classic physics originates in Ancient Greece. The theories Thales, the first physicist, designs gives the discipline of physics its name. Thales believes that Earth is made of only one element: water. Water’s interaction throughout the phases of solid, liquid, and gas gives materials different properties. Although he slows the progress of physics for centuries, Aristotle …show more content…
is regarded as the father of science. Aristotle uses his theory of elements to explain concepts such as motion and gravity. Aristotle believes that the universe is made of only five elements: earth, air, fire, water, and the aether. Physics flourishes during the Renaissance through physicists such as Copernicus, Kepler, and Galileo.
Copernicus discovers the sun’s central location in the solar system.. Kepler develops three laws that explain planetary motion. Galileo discovers that the original state of an object is either at rest or moving with a constant velocity provided that no unbalanced forces are acting upon the object. Galileo understands the acceleration and the impact of gravity on the movement of objects.
Newton, born soon after Galileo, creates the three laws dictating motion and laws called Newton’s Law of Universal Gravitation. Upon discovering the law of universal gravitation, Newton invents calculus, a type of math, for use in his studies. Newton’s knowledge is crucial in the understanding of gravity for modern physics. Albert Einstein, a key figure in modern physics, develops and publishes the Theory of Relativity to describe the non-mechanical state of the universe. After Einstein, quantum theory fills the void for physicists and their …show more content…

The engineering behind an egg drop device requires patience and mental strength. Initially, our group plans to use a Gatorade bottle for the shell and use cotton to protect the egg and rice to help absorb some shock. Our group realizes that there is a high probability that the device would impact with a high impulsive force, thus causing the egg to break due to the impulse of force as the device hit the ground, To combat this issue, the idea of using pool noodles around the sides of the bottle to act as a shock absorber reveals itself.
The experimental phase concludes more cotton was needed, so our group promptly stuffed cotton into every crevice imaginable to add even more absorption power to the device. In its final state, the device comprises itself of a Gatorade bottle with an inner chamber, cotton balls in the inner chamber and all around the exterior of the bottle, rice in between the inner and outer chamber of the Gatorade bottle, and pool noodles around the outside. Upon the device’s drop at seventy-five feet, the conclusion that the device would not work unmasks itself. Once my group discovers that the device doesn’t work correctly, our group uses our knowledge of physics to devise the idea that the issue may lie in the weight of the object, since reducing the weight would lower the momentum and kinetic energy, thus causing less of an impact as a result. A future model of the device would likely be lighter to counteract the higher momentum and energy resulting from a larger mass.

Figure 2: 3D Model Concept Figure 3: The device’s appearance as it currently stands Egg-dropping physics is complex and conceptual. The conceptual side of egg-dropping requires knowledge of free-fall physics. The most basic formula to know is v = d/t, or velocity is equal to the distance divided by the elapsed time. In the test simulation, the device is dropped at a distance of 75 feet or 22.86 meters, and the average elapsed time is 2.223 seconds. Using these two values, substituted into the formula, the velocity is determined to be 10.2834 meters per second. Velocity is a vector quantity with direction and magnitude. In the case of the device, the direction is directly down or 90 degrees below the horizontal and the magnitude is 10.2834. After solving for velocity, one can get the acceleration of the device as it drops from 75 feet. To calculate acceleration, the formula a = v / t, or in other words, acceleration is equal to velocity divided by the elapsed time. Substituting in the values, acceleration roughly equals 4.6259 m/s^2. With the acceleration, the force of the falling object is calculable using the formula f = ma, or force is equal to the mass times the acceleration. When the values are substituted in, the formula determines the force to be 5.3105 Newtons.
The potential energy of the object can be calculated using the formula PE = mgh, or potential energy is equal to mass times gravity times height. Our egg drop device is determined to have a potential energy total of 78.48981 J. The change in kinetic energy is calculable using KE = ½ mvf^2 - ½ mvi^2, or the change in kinetic energy is equal to one half of mass times velocity squared final minus one half of mass times velocity squared initial. The change in kinetic energy is equal to 18.505955223 J..
Momentum derives itself from the formula p = p’, or initial momentum is equal to the final momentum. Momentum is equal to mass times velocity, p = mv, and this formula is also used for the final momentum. Since the egg drop contraption is dropped the initial momentum is calculable to be zero. The final momentum directly prior to it hitting the ground is calculated to be p’=0.350kg * 10.2834m/s is equal to 3.59919 kg*m/s The experiment concludes that the initial momentum of the object is zero, as it is at rest. In contrast, the experiment produces a momentum right before the egg drop contraption hits the ground is 3.59919 kg*m/s or rounded to 3.6kg*m/s. The values the group calculates for the device is charted below.

Under the knowledge of history, engineering, and mathematics, a person can create a convincing device.
In truth, egg-drop uses all four parts of STEM: science, technology, engineering, and mathematics. The historical unit of physics invokes the historical basis of dropping an object into a person’s mind. The engineering process uses a person’s understanding of how outside forces react on an object allows engineers to create a device that can withstand the forces of the universe. The technology portion utilizes a person’s understanding of technological advancements to help aid in the process of creating a device. The science portion explains how the physics of free-fall works by feeding information on the scalars and vectors required to understand a device. Lastly, the mathematics portion of the assignment gives the group raw data that is utilizable to troubleshoot issues that may reveal themselves as the designing process
continues.
