Indonesia is a state that occupies several thousand islands of different sizes. At the same time, about half of them are inhabited by people. The rest of the territory is uninhabited. In total, this country is inhabited by representatives of more than 150 nationalities

When they solve any problems in physics in which there are moving objects, they always talk about friction forces. They are either taken into account or they are neglected, but no one doubts the fact of their presence. In this article, we will consider what the moment of friction forces is, and also give problems for the solution of which we will use the knowledge gained

Statics is one of the sections of modern physics that studies the conditions for bodies and systems to be in mechanical equilibrium. To solve balance problems, it is important to know what the support reaction force is. This article is devoted to a detailed consideration of this issue

Classification of different types of friction forces. Experimentally discovered laws of friction. The nature of the friction forces of rest, sliding and rolling. An example of a horizontally sliding body. Motion of a rigid body in a liquid medium. The force of rolling friction and its comparison with the force of sliding friction

Any movement in nature and technology, which involves the presence of physical contact between solid bodies, is accompanied by friction. In this article, we will give examples of the friction force and show in which cases it plays a useful role, and in which it is undesirable

Without the force of friction, people would not be able to move objects, pass them from hand to hand, and just hold them. What is the secret of this phenomenon and how does the force of friction work? Let's find out

Friction is a physical phenomenon that a person struggles with in order to reduce it in any rotating and sliding parts of mechanisms, without which, however, the movement of any of these mechanisms is impossible. In this article, we will consider from the point of view of physics what is the force of rolling friction

What is temperature, what does this physical parameter mean, how is it measured? We will answer these and other questions in the article

How to write an abstract? Many people ask this question, because the so-called "summary" ("description" from English) may be needed both for an article, and for a program or for any project. Depending on the details, the annotation may have special requirements. We will consider them
