Meanings of translational motion in English

In the gaseous state, as we have seen, the translational motion of the molecules is relatively enormous, the molecules being widely separated.

Material and methods: Organ motion was described by normally distributed translational motion, with its magnitude characterised by the standard deviation (SD) of this distribution.

The translocation step may be characterized by rotational as well as translational motions of HIV-1 RT relative to the DNA double helix.
