Continuum mechanics

Newton's Second Law: It describes what happens to the body when it is affected by force, as it shows the relationship between the force affecting the body, and the movement acquired by the body. Through the study of Newton's first law, we see that in the absence of an effective force on an object or the existence of a group of balanced forces affecting it, This body will be in a state of stillness or regular movement in the straight line. We continue to study the movement of objects when a force…

An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…

Aim Simple Pendulum Experiment The aim of the experiment was to determine the effects of two factors (the length of a pendulum and the hanging mass of a pendulum) on the period of oscillation of the simple pendulum and to determine the value of g, the acceleration due to gravity. Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand,…

How do speedometers work? A: A speedometer is a gauge that measures the instantaneous speed of a vehicle. Speedometers became standard in all motor vehicles in 1910 Speedometers were created by the Croatian engineer Josip Belušić in 1855 Uses the rotation of the wheels to work When the cars engine turns over the drive shaft spins to turn the wheels The speedometer cable which is powered by the driveshaft also spins A magnet located inside the speed cup (made of aluminum) of the car spins at the…

The similarities and differences of Kinetics of a Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a…

The Father of Modern Science: Galileo Galilei Galileo Galilei is an important historical figure who is known as the Father of Modern Science. He was a polymath meaning he excelled in many sciences. He was a physicist, an astronomer, a mathematician, and an excellent inventor. Galileo greatly affected history and if he had not made his discoveries it is possible that we could be living in a very different world today. In the beginning… Galileo Galilei was born on February 15, 1564, in Pisa, Italy…

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…

In 1905 German physicist Albert Einstein published the first paper of a new age of Physics. His theory of special relativity, followed by general relativity and the Einstein Field Equations in 1915, and the Copenhagen interpretation of quantum mechanics in 1925 combined to form a more significant shift in natural philosophy…

Imagine, if you were not yourself, yet at the same time you were. Imagine that you had led a completely different life. Maybe you were a soldier, an engineer, a banker, or maybe you did nothing with your life. What if you were born a with a different name, different gender, a different race; what if you were not born at all. Imagine a world where the American Revolution never happened, The Allies fell to the Axis, or the Cold War ended in nuclear annihilation. However, none of these scenarios…
