Web[The crossproduct of two vectors is properly called a pseudovector because of this "anomalous" behavior.] Is the cross product of two pseudovectors a vector, or a pseudovector? Name two pseudovector quantities in classical mechanics. (d) How does the scalar triple product of three vectors transform under inversions? In physics, pseudovectors are generally the result of taking the cross product of two polar vectors or the curl of a polar vector field. The cross product and curl are defined, by convention, according to the right hand rule, but could have been just as easily defined in terms of a left-hand rule. See more In physics and mathematics, a pseudovector (or axial vector) is a quantity that is defined as a function of some vectors or other geometric shapes, that resembles a vector, and behaves like a vector in many situations, … See more The definition of a "vector" in physics (including both polar vectors and pseudovectors) is more specific than the mathematical … See more One way to formalize pseudovectors is as follows: if V is an n-dimensional vector space, then a pseudovector of V is an element of the (n − 1)-th exterior power of V: ⋀ (V). The pseudovectors of V form a vector space with the same dimension as V.

WebOct 9, 2024 · The cross product has a "handedness" which affects the sign, but if you have two cross products, you get two sign changes and the effect of the convention disappears. My understanding is that (in the cases I know about) measurable quantities are physically related in such a way that the sign convention cancels out. WebSince the dual of the pseudoscalar is the product of two "pseudo-quantities", the resulting tensor is a true tensor, and does not change sign upon an inversion of axes. The situation is similar to the situation for pseudovectors and anti-symmetric tensors of order 2. The dual of a pseudovector is an anti-symmetric tensor of order 2 (and vice ...
