formulele

Formulele, in Romanian definite plural form of formulă, refer to expressions that encode rules or relationships used to compute values or to describe the composition of substances. They appear across mathematics, physics, chemistry, and engineering, and they can be symbolic rules, notations of a relationship, or compact representations of a process.

In mathematics and science, formulas describe how quantities relate to each other. A formula may be algebraic, geometric, or trigonometric, providing a rule to obtain a result from given inputs. In physics, formulas express fundamental laws, such as Newton’s second law F = ma or the energy–mass relation E = mc^2. In chemistry, formulas denote the composition of substances, for example H2O for water or CO2 for carbon dioxide. Formulas differ from equations in that a formula specifies how to compute a value, while an equation asserts that two expressions are equal.

Formulele are central to calculation, modeling, and problem solving. They can be rearranged to solve for different variables, and their validity rests on underlying assumptions and units. In practical use, formulas require appropriate input values and consistent units to yield meaningful results. They also underpin tools found in education, engineering, and computing, including calculators and spreadsheet programs, where formulas automate computations based on cell inputs. The concept is foundational in science and a common part of everyday numerical reasoning.
