In the m9c free fall acceleration lab we were to determine if mass or distance of an object falls effect on gravitation acceleration that the object experiences. The experiment was used to investigate the theory weather the heavier the object that it is will fall faster or not. The method that was used to find gravity was through the derived version of kinematic definitions. The overall result in the experiment concluded that distance and mass does not effect on the gravitational acceleration…
Albert Einstein’s Change of Heart: From Pacifism to the Atomic Bomb
Beyond doubt, Albert Einstein is one of the most famous scientists of the 20th century. His name is the first one that comes to mind when one looks for genius. This is not without reason since we owe him most of what we know about space and time. Even though he usually appears with his smiling face, fluffy white hair and pipe in his photographs, when one looks deep into his eyes, it is striking to sense some sort of sorrow…
The main objective of this lab is to observe the behavior of a metal block while experiencing uniaxial translation and oscillation in respects to time to calculate the acceleration, spring constant, and damping factor. The experiment was split into two different labs. Part one, the drop test, to take the block to a fixed height and drop it. This would then allow us to calculate the friction force, along with the acceleration of the metal block. Part two, the bounce test, is…
Marie von Ebner Eschenbach once said, “In youth we learn; in age we understand.” I agree with this quote. During youth we learn and experience a lot of our “firsts.” Our first word, first steps, first bully, first fight, first kiss, first relationship, first love and first time. Thus, when we get older we evolve and understand more of what life is and what is expected of you. Though I am merely fifteen years old and haven’t graduated high school yet, I’ve matured and have learned from my…
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.
Physics originates in its classical form in Ancient Greece. Thales was the first physicist. The theories Thales made gave…
C.S. Lewis begins his novel Mere Christianity by discussing the Law of Human Nature and various other laws that are important to his discussion. Lewis states that people must be aware of a Law or Rule of fair play or else there would be much more quarrelling among humans. This Rule or Law used to be known as the Law of Nature; however, laws of nature today will usually refer to things such as gravitation, heredity, or the laws of chemistry (Lewis, 4). The Law of Nature, when concerning issues of…
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…
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.

The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. :
∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ
where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity.
The first term in the…
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…
