The word 撞击 is formed through the combination of two individual characters, each contributing a core meaning of forceful contact. The first character, 撞, primarily means "to bump against", "to collide with", or "to strike". The second character, 击, carries the meaning of "to hit", "to beat", or "to attack". When joined, they create a single, more vivid and intensified concept where their meanings converge and reinforce each other, picturing a powerful, direct act of hitting or colliding, much like two distinct images of impact merging into one stronger, unified action.
