The universe was born from nothing? At the beginning of everything, there was no matter and it appeared as a consequence of the evolution of the cosmos. Something we are still trying to understand. Even though matter didn’t always exist…
What is Gravity? Gravitational force is the force that large bodies, such as planets, exert on smaller objects. Gravitational force attracts objects thrown toward the Earth and also keeps the Moon in its orbit. The term Gravitational force is used…
What is radiation? Radiation is various types of energy in the form of particles or electromagnetic waves that travel through space. The radiation has different compositions and origins. Radiation is a physical process of emission (output) and propagation (displacement) of…
In physical terms, time is what clocks measure. This may sound unsatisfactory, but this definition corresponds not only to our everyday understanding, but also to Einstein’s theory of relativity. Einstein, after all, said that time is relative, and by that…
Einstein is considered the greatest of theorists, alongside Isaac Newton, the father of classical mechanics. His name has become synonymous with genius. To commemorate him, we have compiled this list of his main contributions to physics: 1. Brownian motion:This discovery,…
We will start by explaining the physical phenomenon on which the temperature that something can have depends. When the particles of an object move a lot, they generate heat, and the entity has a higher temperature. When particles move less,…
To keep it simple, when it comes to magnetism there are three main types of materials: Ferromagnetic: Which are strongly attracted by magnetic fields, and are mainly alloys of iron, nickel and cobalt; note that these three metals are adjacent…
Who is the real father of electricity? Benjamin Franklin was interested in many areas of science, made many discoveries, and invented many things, including bifocal glasses. He believed that electricity had positive and negative elements, flowed between these elements, and…
We use several types of energy on a daily basis. The most important are: mechanical energy, electrical energy, thermal energy, chemical energy, nuclear energy, light energy and sound energy. Remember that energy is a concept used in several scientific areas,…
Gravitation is one of the four fundamental forces of nature. Of all four basic forces, gravitational force is the one that we are particularly familiar with. The other forces are the weak nuclear force, electromagnetic force and strong nuclear force.…
