An accident is an undesirable incidental and unplanned event that could have been prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence. Most scientists who study unintentional injury avoid using the term accident and focus on factors that increase risk of severe injury and that reduce injury incidence and severity .
Physical examples of accidents include unintended motor vehicle collisions or falls, being injured by touching something sharp, hot, electrical or ingesting poison. Non-physical examples are unintentionally revealing a secret or otherwise saying something incorrectly, forgetting an appointment, etc. (source : wikipedia
