What is the Mathematical equivalent of the definition of vectors in physics?Physics has an additional requirement to define physical quantities as vectors i.e. if they are invariant under rotation of the coordinate system for example quantities like force, velocity etc. How does it correspond to the mathematical formulation? Is it a subset of vector spaces? Is it an alternate characterisation to the axioms of vector space and can it be proved from the former axioms From wikipedia: A vector space over a field F is a set V together with two operations that satisfy the eight axioms. The first operation, called vector addition or simply addition + : V × V -> V, takes any two vectors v and w and assigns to them a third vector which is commonly written as v + w, and called the sum of these two v

An object moving in the xy-plane is acted on by a conservative force described by the potential energy function ${\displaystyle U(x,y)=\alpha (\frac{1}{x^2}+\frac{1}{y^2})}$ where ${\displaystyle \alpha }$ is a positive constant. Derivative an expression for the force expressed terms of the unit vectors ${\displaystyle \overrightarrow{i}}$ and ${\displaystyle \overrightarrow{j}}$.
