Definition:Right-Hand Rule/Axial Vector
< Definition:Right-Hand Rule(Redirected from Definition:Right-Hand Rule for Axial Vector)Jump to navigation Jump to search
Let $\mathbf V$ be an axial vector acting with respect to an axis of rotation $R$.
Consider a right hand with its fingers curled round $R$ so that the fingers are pointed in the direction of rotation of $\mathbf V$ around $R$.
The right-hand rule is the convention that the direction of $\mathbf V$ is the direction in which the thumb is pointing:
Also known as
The right-hand rule for axial vectors is also known as the right-hand screw rule.
This is because it defines the direction of motion of a conventional screw: turn it in a clockwise direction and it screws in.
