physikalische

Physikalische is the inflected form of the German adjective physikalisch, used to describe phenomena, properties, or disciplines related to physics or the physical aspects of matter. In everyday and technical German, physikalisch denotes what pertains to the laws and properties of nature described by physics, as opposed to chemical, biological, or geometric meanings.

The form physikalische is used when the modified noun is feminine singular in nominative or accusative, plural in many cases, or in other inflected positions according to German adjective endings. Examples include die physikalische Eigenschaft (feminine singular, nominative), eine physikalische Größe, den physikalischen Prozess (masculine singular, accusative), and die physikalischen Gesetze (plural). In compound terms, physic-related concepts appear as Teil von phrases such as physikalische Eigenschaften, physikalische Gesetze, or physikalische Messungen. A well-known field is Physikalische Chemie, also called physical chemistry in German, which studies the physical principles underlying chemical systems.

Usage guidance: physikalische acts as a descriptive modifier and is not capitalized unless it begins a sentence or appears in a title or proper noun. Its counterpart forms adapt to gender, number, and case just like other German adjectives.
