Your question is somewhat difficult because of conflicting understandings. A body that is in rest has no velocity - which is different than from a body being static (a state of rest).
Take, for instance, the speed of an electron - light. It travels at a speed of 186,000+ miles per second. You can imagine this electron traveling thru the vacuum of space in a strait line. However, electrons orbit atoms in a cirrcular pattern. The speed of the electron has not changed. It still orbits the atom at the speed of light. This is based on C as the speed of light is constant. One electron is “free”, the other is “contained.” One electron is said to be static (a relative form of rest), the other is not. Yet both are moving at the speed of light.

Relative states of vacuum have the ability to change the volicity of a body. Vacuum, however, is not the only force with this ability. Various forms of pressure, gravity and many other forces have infleuence of velocity.

I hope this may help you. Good Luck.
