Easy explanation
Bang usually describes a loud hit or noise. It can also be a shout for a sudden sound (Bang!). In slang, it can mean to have sex—this use is rude. There’s also bangs (US) for a front fringe of hair, which is unrelated to the loud-noise meaning.

Register and tone
Neutral for hit/sound; playful for interjection; informal for adverbial uses; vulgar for the sexual verb. Avoid the vulgar sense in professional or polite contexts.
