2. In physics, the tendency of a body to remain at rest or in motion until acted upon by an outside force: The inertia of many astronomical objects have been the same for centuries.
3. Inactivity; inability to move spontaneously; sluggishness: Old age has a strong influence on the inertia of most people. In fact, the older people become, the less inertia they have.
4. Resistance or disinclination to motion, action, or change: The inertia of an entrenched bureaucracy is nothing new.
5. Etymology: used as a term in physics during the 17th century by the German astronomer and physician, Johann Kepler (1571-1630); from Latin inertia, "unskillfulness, idleness"; from iners, inertis, "unskilled, inactive"; from Latin in-, "not + ars, artis, "skill, the method, way, an art, faculty". Used in Modern Latin by Newton (1687).
The sense of "apathy" was first recorded in 1822.

2. Characteristic delay of a current in an electric circuit in reaching its maximum value, or in returning to zero, after the source voltage has been removed or applied.
An oxymoron from Horace telling us that it often takes a lot of work to appear to keep busy doing nothing.
Moving objects usually grind to a halt because there is a force, or friction, trying to stop them, but if the force of friction is taken away as in space, then Newton's first law explains the function that keeps the stars, planets, and moons continually moving.
