gördülést

Gördülés is a Hungarian term that translates to "rolling" or "tumbling" in English. It generally refers to the act of moving by turning over and over on a surface. This motion can be applied to various objects, from a ball or a log to a person or an animal.

In physics, gördülés describes the motion of an object that is both rotating about its own axis and translating along a surface. This type of motion is distinct from pure sliding, where an object moves without rotating, or pure rotation, where an object spins in place. The interaction between the rotating object and the surface typically involves friction, which allows the rolling motion to occur. Without sufficient friction, an object might slip rather than roll.

The concept of gördülés is fundamental in understanding mechanics and has applications in many areas, including engineering and sports. For instance, the wheels of a vehicle use gördülés to facilitate movement. In sports, activities like gymnastics often involve complex forms of human gördülés. The efficiency of gördülés often depends on factors such as the object's shape, mass distribution, and the nature of the surface. In everyday language, gördülés can also describe a less controlled or more chaotic movement of something falling or descending, akin to tumbling down a hill.
