Classical Physics
Contributions by Anika Jones Fall 2022
Classical physics encompasses the theories of mechanics, electromagnetism and thermodynamics that help explain a large part of the everyday things that go on around us on a macroscopic scale, which predates Modern Physic theories of quantum and relativity that explains things that are on the smaller, microscopic level.
In classical physics, observations about things can be seen using the human senses. For example, Newton’s observation that gravity caused things to fall to the ground leading to his three physics laws that are still relevant today. Classical physics helps to answer the whys about the things that we observe and experience in the world around us, from the path of the sun in the sky to the reaction of boiling a pot of water.
Classical physics laid the groundwork for modern physics theories to understand those things around us that we can not see in the traditional way but observed behaviors that are happening on a microscopic level.

This topic helped to differentiate between modern physic theories and classical physic theories. I was able to understand where classical physics stops, and modern physics begins. It put things into perspective with usage of equations and application on the macroscopic scale versus the microscopic scale.
As a physics major, this distinguish is important in the approach to solving problem for large bodies that are moving slower than the speed of light versus subatomic particles moving at the speed of light.
Classical physics theories are still the basis for theories in modern physics, for example in classical physics any frame moves at a constant velocity if there is no external force or the object is at rest, in modern physics (special relativity) an inertial frame is a frame of reference when a free object experiences zero net force and moves at constant velocity relative to the observer.
Industrial application of classical physics can be seen in electric motors, elevators, moving floors to escalators.
History
Classical Physics predates 1900 physics theories that help us understand phenomena around us, all thanks to works of Sir Isaac Newton, Galileo Galilei, and James Maxwell just to name a few. From their observations and research, we have a better understanding of how and why things operate the way they do around us that led to technological advances that we enjoy today in making a way of life easier.
Without any fancy and high-tech equipment, these scientists use simple observations and equipment to build the foundation of physics as we know it today that has been proven over hundreds of years to still be valid. From Newton’s law that force is equal to mass times acceleration to Maxwell’s equation for electromagnetism. Without their contributions our world today would look a lot different.
