Key Differences

Vomit refers to the involuntary expulsion of stomach contents through the mouth, often due to illness, food poisoning, or other medical conditions. Upchuck is a casual, slang term for vomiting, used in informal contexts to describe the same action.
Vomit is the more commonly used term in medical and formal contexts, such as hospitals or health discussions. Upchuck, on the other hand, is used in informal speech and often carries a less serious connotation.
While vomit can be associated with various health issues, including gastrointestinal disorders, infections, or pregnancy, upchuck is typically used to describe a less severe or more casual instance of vomiting, like after overeating or due to mild nausea.
Vomit is derived from the Latin word "vomere," highlighting its longstanding medical usage. Upchuck is an American slang term that gained popularity in the 20th century, emphasizing its informal and colloquial nature.
In terms of usage, one might say, "I need to see a doctor because I vomited last night," while a more casual context might involve, "I upchucked after the rollercoaster ride."
