For example, how could equations like be rotationally covariant if force is a contravariant vector? I know this is strictly speaking more of a mathy question, but I still figured this was the best place to ask this question. Answers and Replies Feb 1, 2013 #2A vector's components change scale inversely to changes in scale to the reference axes, and consequently a vector is called a contravariant tensor. In contrast, a covector, also called a dual vector, has components that vary with the basis vectors in the corresponding vector space. It is an example of a covariant tensor. Covariance and correlation are two statistical tools that are closely related but different in nature. Both techniques interpret the relationship between random variables and determine the type of dependence between them.
