Question

what is orthogonal vector in physics?

Answer 1

In geometry, two Euclidean vectors are orthogonal if they are perpendicular, i.e., they form a right angle. Two vectors, x and y, in an inner product space, V, are orthogonal if their inner product is zero. ... A term rewriting system is said to be orthogonal if it is left-linear and is non-ambiguous.

Answer 2

Two vectors, x and y, in an inner product space, V, are orthogonal if their inner product is zero.
