Angular displacement

The angular displacement – also called angle of rotation, rotational displacement, or rotary displacement – of a physical body is the angle through which the body has rotated around a centre of rotati

Right-hand rule

In mathematics and physics, the right-hand rule is a convention and a mnemonic utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product
Angular displacement
…of rotation, which always exists by virtue of the Euler's rotation theorem; the magnitude specifies the rotation in radians about that axis (using the right-hand rule to determine direction). This entity is called an axis-angle. Despite having direction and magnitude, angular displacement is not a vector because it…
