To integrate my previous article, in this section we will deal with complex problems that would be extremely hard to solve using newtonian mechanics. We will start with very simple problems and then gradually build up to harder problems. Of course we won’t solve 100 levelled pendulum kinematics but that’s only because it takes too much time and also there is no point in solving for more than two levels pendulum kinematics sinc...

This article uses advanced mathematical techniques. Deep calculus understanding is required as well as some knowledge in newtonian mechanics and in the concept of energy.

What is wrong with Newtonian mechanics ?

There is no doubt that Newtonian mechanics did succeed in describing the macroscopical dynamics of the world, but the more complex systems we encounter and the more variables that we introduce, the harder it becomes...

Most of the energy that we generate today comes from generators because a generator can transform the kinetic energy into electrical energy.  Now kinetic means motion, so therefore where do we get the motion from? A simple turbine has blades and rotates but then how do you get the blades to rotate? Well, you can let the wind or the water to the job.

So you build a dam to let the water flow to the turbine, and that is hydroelec...

Since I was a kid I loved observing airplanes flying in the sky. My life can be resumed to airplanes in a way. But jet flights were always my favorites. I am from Brazil so I would watch the now decommissioned Mirages 2000 fly all the time. And the coolest of all I have probably seen only once in real live, when the fighters break the sound barriers. But this also made me quite curious about sound waves. How do sound waves beh...

Hello everyone and welcome back to another Athenology post. This time we’ll be taking a look at some physics, and, as you might know from the title: Sandia’s z machine. And by now you are maybe asking yourself: What is it all about anyway? It is a tool created by Sandia National Laboratory, this project started by 1960 and is used by scientists for many purposes that we’ll see further on. What it does basically is using electr...

An object's gravitational energy is proportional to its position in height. When the tennis ball is lifted

from the ground, it gains potential energy and right before it is released, the energy gets fully transformed into kinetic energy and once the tennis ball bounces off the ground, some of that energy gets absorbed into sound and heat. The energy lost is in fact a constant fraction of the initial energy before t...

Hi! In order to understand this blog post, please read the previous one, Electric fields. In this post I will talk

about Coulomb's law, electric current and energy and charge.

Coulomb’s law allows us to calculate the electric force between the electric force between two point charges. A force of equal magnitude acts on both charges, but in opposite directions. The magnitude of the force, F, between two isolated point charges, q...

A black hole is a place in space where gravity pulls so much that not even light can get out. Since no light can get out black holes can't be seen. They are invisible. Certain space telescopes can detect black holes through special tools. These special tools can observe how stars close to black holes act differently than other stars. Scientists can see how the gravity of black holes affect the stars close to them. Black holes...

Background information 

The reason to the making of this experiment was to find the equation of the Pendulum and determine what affects the period the most with different constant and changeable factors such as length, angle and mass. A pendulum is an object suspended on a fixed point that can only move through given force transformed from potential energy from my hand to kinetic energy making the pendulum swing from side to si...

The Andromeda Galaxy or Messier 31 (M31) is approximately 2.5 million light years away from Earth and its the nearest major galaxy to the Milky Way. Before It was estimated to contain approximately 1 trillion stars, more then the double of stars in the Milky Way, around 300 billion stars. And it is also the largest galaxy in our Local Group. But according to new studies by Monthly Notices of the Royal Astronomical Society, the...
