Ejection refers to the act of forcefully removing or expelling something from a particular place. In various contexts, such as aviation, ejection can describe the process of a pilot using an ejection seat to escape from an aircraft in an emergency. This mechanism is designed to propel the pilot away from the aircraft quickly and safely. In sports, ejection often occurs when a player is removed from a game due to unsportsmanlike conduct or rule violations. Referees or officials have the authority to issue an ejection to maintain fair play and ensure the safety of all participants involved.
