27 "in space there is not gravity" "The terms gravitation and gravity are mostly interchangeable in everyday use, but in scientific usage a distinction maybe made. "Gravitation" is a general term describing the attractive influence that all objects with mass exert on each other, while "gravity" specifically refers to a force that is supposed in some theories (such as Newtons) to be the cause of this attraction. By contrast, in general relativity gravitation is due to space-time curvatures that cause inertially moving objects to accelerate towards each other.
