Moment of Inertia

Inertia

Inertia in physics is the ability of bodies to maintain a state of motion for a certain time in the absence of external forces. However, the concept of inertia is often used not only in physics but also in our daily lives. For instance, the inert person is the person who does not show any initiative at all. Inert persons only do what others tell them, and they do it extremely slowly, without any enthusiasm. “It moves by inertia,” we say when we want to emphasize that something is being done without any meaning, but simply because of a habit acquired over the years.

Brownian Motion

Brownian Motion

Brownian motion (or Brownian movement) is the chaotic and random motion of small particles (usually molecules) in different liquids or gases. The cause of Brownian motion is the collision of small particles with other particles. What is the story of the discovery of Brownian motion? Why is Brownian motion so important in physic and chemistry? What are some examples of Brownian motion in real life? Read about all this in our article.

Oxygen

Oxygen

Oxygen plays a leading role among all the known chemical elements. Life on our planet wouldn’t arise without oxygen. Oxygen is the most common chemical element on Earth, accounting for 49% of the total mass of the earth’s crust. Oxygen is also part of the Earth’s atmosphere; part of the composition of water, and the composition of more than 1,400 different minerals, such as basalt, marble, silicate, silica, etc. About 50-80% of the total mass of tissues, both animals and plants, consists of oxygen. The important role of oxygen for the breathing of all life is well known.

Diffusion

Diffusion

The word “diffusion” of Latin origin – “diffusio” in Latin means “spread, dispersion.” In science, diffusion is the process of the interpenetration of microparticles upon the contact of different materials. The academic definition of diffusion is: “Diffusion is the mutual penetration of the molecules of one substance into the intermolecular spaces of another substance due to their chaotic motion and collision with each other.”
