What is difference between 'go', 'going', 'gone' and 'goes'?

Go - [present simple use the infinitive]- I need to go and wash the car. Goes - [present simple third person/voice, best way to explain this is an habitual action]- He goes to the car wash once a week. Going [present simple continuous] I’m going to the car wash, [present continuous third person/voice]- He’s going to the car wash. Gone. [present perfect tense ]- he has gone to to doctor's for a check up [past perfect third person/voice]- He had gone to the doctor's last Tuesday for a check up. Hope it helps a little.
