Almost all of them can be described fully by either a scalar (just knowing the amount is enough) or vector (where the amount and also which way it points is important) field.

Hairy black hole: A black hole solution that supports additional field structures (such as scalar or vector hair) beyond the classical parameters of mass, charge, and angular momentum.

The problems arise when these quantities interact mathematically. Vector fields can be multiplied by scalars or by each other in two different ways, known as a dot product and a cross product.

We show that every Lr-vector field on Ω can be uniquely decomposed into two spaces with scalar and vector potentials, and the harmonic vector space via operators rot and div, where Ω is a bounded ...

Motion and forces Scalar and vector quantities - Edexcel Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors.
