Lecture 13 Purdue University, Physics 220 5 Rotations: Axes and Sign When we talk about rotation, it is implied that there is a rotation “axis”. This is usually called the “z” axis (we usually omit the z subscript for simplicity). Use the right-hand rule to determine the direction of rotation. Counter-clockwise (increasing θ ) is usually called positive. Clockwise (decreasing θ ) is usually called negative . z + ϖ
