Six degrees of freedom

When conversing about motion mechanics we frequently refer to the six degrees of motion, or 6-DOF. 6-DOF includes three axes of translational motion and three axes of angular (rotational) motion.

In the attached video a cube-like object is pictured. You can see three straight-line arrows depicting the cube's three DOF translational motion options, and three arced-line arrows depicting the cube's three DOF angular motion options. The translational motions occur "along" the depicted axes, the angular motions are said to occur "about" the depicted axes.

6 DOF (0 min 16 sec)

Along with defining an object's type of motion, 6-DOF also can refer to the application of multi-DOF disturbances forces imparted to an object.
