Actually, a moving body does NOT stay in motion unless it is orbiting,
and even then it eventually meets enough interference to be slowed and
falls into the atmosphere of some sun, star or planet.

Newtons first law of inertial motion is a theoretical (fictious)
motion, and does not last: Like a magnet on a steel plate, when the
force to move an object is removed, the object will stop, because there
are _no_ really friction free surfaces.
