Stereometry is a section of geometry that studies figures that do not lie in the same plane. One of the objects of study of stereometry are prisms. In the article we will give a definition of a prism from a geometric point of view, and also briefly list the properties that are characteristic of it. Last modified: 2025-01-13 07:01

In the general course of physics, two of the simplest types of movement of objects in space are studied - this is translational motion and rotation. If the dynamics of translational motion is based on the use of such quantities as forces and masses, then the concepts of moments are used to quantitatively describe the rotation of bodies. In this article, we will consider by what formula the moment of force is calculated, and for solving what problems this value is used. Last modified: 2025-01-13 07:01
