Etymology: The ancient machine at the root of this word was a giant crossbow. The Latin "ballista" was a siege engine that hurled stones or bolts, and its Greek ancestor "ballistes" came from "ballein", "to throw". Scholars in the early modern period built on that classical name, creating the New Latin "ballistica" as the science of such missiles, and English took the subject over in the form "ballistics". The noun is a little unusual in its grammar. The "-ics" ending has the same pattern as "physics" or "mathematics", which name fields of study, so "ballistics" behaves like a single subject even though it looks plural. The form was modelled on the adjective "ballistic", which is itself a derivative of "ballista", so the word is layered: an ancient weapon's name, filtered through a Latin scientific label, then clothed in an English subject-name ending.
