These thrusters will produce a force roughly the same as whispering in somebody's ear which should be just enough to keep the two spacecraft moving at a relative velocity of less than 20 microns a second.

ECONOMIST: Birds of a feather

The research is the first to show a direct link in Antarctica between the behaviour of the lakes and the velocity of the ice moving overhead.

Unlike Apple, which places increasingly tight control over what people can put on iPads, Google seems to want as many outsiders as possible to put anything they want on Android, with the fastest possible velocity of successful apps moving through the system (love an app, and you can automatically Tweet a link to its app store location).

Because it has less to do with standing still and more to do with how you use velocity, energy, and mass to keep moving forward.
