What is the difference between vomiting and regurgitation?

Vomiting: vomiting is the involuntary forceful expulsion of stomach contents, where regurgitation can be voluntary or involuntary of food that comes up , such as with a burp or belch.

Vomitting: Vomiting or throwing up is voluntarily or involuntarily forcing the contents of the stomach up through the esophagus and out of the mouth. Regurgitation is the sensation of acid backing up into your throat or mouth. Regurgitation can produce a sour or bitter taste, and you may experience a "wet burp" or even vomit some contents of your stomach, but usually much smaller amount than typical vomittin

Hmmm: Vomiting is normally digested material being expelled throughout the body onto the floor or a person etc Regurgitation is digested material from the stomach into the esophagus but tends to stay inside the body.

Nausea/force: With vomiting you have a sense of nausea and a forceful expelling of the stomach contents. With regurgitation the food just comes back up, no warning and not necessarily forceful.
