What tense is used for "go" in "you see it go away"? [duplicate]

I understand it's not the present tense, else it would be "goes". Is the sentence grammatically correct? If so, does it mean "you are seeing that it is going away"?

Solution 1:

Verbs of perception (see, hear, notice, etc.) are followed by an unmarked infinitive — technically a present infinitive, but the past infinitive can't be used in this construction — or a present participle. I saw him go. I saw him going. The difference is a slight emphasis either on the action as a whole (infinitive) or as a progressive activity one observes (present participle). Though in the objective case, "him" is actually the subject of the infinitive "go." https://dictionary.cambridge.org/de/grammatik/britisch-grammatik/verb-patterns/hear-see-etc-object-infinitive-or-ing
