A constant is a value that does not change within a given context, equation, or process. In mathematics, it can be a fixed numerical value, such as 3, 10, or specific numbers like π or e. In physics, constants often describe fundamental properties of nature, like the speed of light or the gravitational constant. Unlike variables, which can take on different values, a constant remains the same throughout a calculation, model, or experiment. Constants are essential for defining formulas, laws, and relationships, providing stability and reference points in scientific and mathematical reasoning.
