fyzikálním

Fyzikálním is the instrumental singular form of the Czech adjective fyzikální, meaning physical or relating to physics. It is used to modify nouns in the instrumental case, for example: fyzikálním zákonem (by a physical law), fyzikálním měřítkem (by a physical scale), or fyzikálním způsobem (in a physical manner). The base form fyzikální is used in other cases and genders, such as fyzikální vlastnost (a physical property) or fyzikální problém (a physics-related problem).

The term describes properties, phenomena, principles, quantities, or disciplines connected with physics or the physical world. It is common in scientific, engineering, and educational contexts, and when distinguishing physical aspects from biological, chemical, or mathematical ones. Examples include fyzikální vlastnosti materiálu (physical properties of a material) or fyzikální experiment (a physics experiment).

Etymology: fyzikální derives from fyzika (physics), which in turn comes from the Greek physis (nature) via Latin physica. The Czech term was formed and integrated into the language to denote the physical as opposed to other domains of science.

Related forms include the adverb fyzikálně (physically, in a physical manner) and various inflected forms for different gender and case. In Czech-language texts, fyzika and fyzikální are standard terms in academic and technical writing, helping to specify the physical aspects of objects, systems, and laws.
