In advanced theoretical physics, a modulus is a scalar field with no potential energy. See moduli.
In materials science, modulus (or elastic modulus) is a measure of the stiffness of a material. See also Young's modulus
In mathematics, the modulus of a number (real or complex) is its absolute value. The modulus of a vector is its length.
The word modulus also denotes the number by which two numbers are said to be congruent in modular arithmetic.
The word modulo, which is the Latin ablative of modulus, has many meanings (all somewhat related) in mathematics and computing. See modulo.
Another mathematical sense is the modulus of continuity.
