Explore The Physical Principles Of Classical Physics

Explore the physical principles of classical physics

Explore the physical principles of classical physics. Instructions In a two-page paper, identify the classical physics principles contained within the following scenario. Explain how these principles connect to work done by Galileo or Newton. Finally, consider the different fields in which Galileo and Newton did research, and give an example of one of these fields in use in your life. For instance, Newton developed the field of optics. If you wear glasses or contact lenses, you are using Newton's physical optics theories every day. Aside from glasses or contacts, how do the theories of Newton or Galileo affect you in your daily life? Scenario Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination. She could watch the Sun setting in the west. Over the Eastern horizon peeked a full moon, just rising, displaying its cratered face. As the plane neared the ground, Mandy could not help but think that she was in a giant metal object hurtling through the sky. Without the specific shape of its wings, the plane would fall to the ground no differently than a large metal projectile.

The scenario presented encapsulates fundamental principles of classical physics, primarily Newtonian mechanics, celestial mechanics, and optics. These principles can be traced back to the groundbreaking work of Galileo and Newton, whose research laid the foundation for understanding motion, gravity, and light, all of which are integral to everyday phenomena, including modern air travel and optical devices.

At the core of the scenario is the concept of motion and gravity, governed by Newton's laws of motion and universal gravitation. Newton proposed that the same gravitational force that causes an apple to fall from a tree also governs the motion of celestial bodies like the Moon and the Sun. When Mandy observes the Sun setting and the Moon rising, she witnesses these celestial movements governed by Newtonian gravitation and the principles of elliptical orbits. Newton's law of universal gravitation posits that every mass attracts every other mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. This explains the predictable orbits of celestial bodies and the descent of objects, including an aircraft, within Earth's gravitational pull.

Moreover, the airplane's flight itself involves principles from Newtonian physics. According to Newton's third law of motion, the thrust generated by the airplane's engines pushes air backward, propelling the aircraft forward. The wings of the plane are shaped to generate lift, which is explained by Bernoulli's principle connected to fluid dynamics, a subset of classical physics, demonstrating how differences in air pressure above and below the wing surface produce an upward force counteracting gravity. Without the understanding of these principles, as Galileo and Newton explored, safe modern aviation would be impossible.

Optics, another field profoundly impacted by Newton, also plays a significant role in daily life. Newton's work in physical optics, particularly his corpuscular theory of light and the study of how light interacts with lenses, directly applies to the development of glasses, contact lenses, telescopes, and cameras. For individuals wearing corrective lenses, Newton's optical theories help improve vision clarity, enhancing everyday activities such as reading, driving, or using electronic devices.

Beyond physical devices, Newton and Galileo's principles influence our comprehension of natural phenomena and technological innovations. Galileo's work with telescopes expanded our understanding of celestial bodies and motion, influencing modern astronomy and space exploration. For example, Galileo's discovery of moons orbiting Jupiter demonstrated evidence of celestial bodies orbiting objects other than Earth, challenging the geocentric model and paving the way for the heliocentric model. This understanding impacts satellite technology, GPS systems, and space missions.

In my daily life, these principles manifest in numerous ways. For instance, the use of GPS navigation relies on principles of physics, including Einstein's relativity, but Newtonian mechanics still underpin the calculations of satellite orbits and ground-based positioning systems. Additionally, the safety features in vehicles, the design of sports equipment, and even the way electronic devices function are influenced by classical physics principles stemming from Galileo and Newton's initial discoveries.

In summary, the classical physics principles illustrated in Mandy's scenario—motion, gravity, and optics—are deeply rooted in the pioneering research of Galileo and Newton. Their work not only explains the behavior of celestial and terrestrial objects but also underpins modern technology and daily life processes. From the flight of an airplane to the corrective lenses we wear, the legacy of these scientists continues to shape our understanding and interaction with the physical world.
