A more thorough explanation:

Definition: Ejection is the act of being forced out of a place by law or physical force.

Examples:

• When the landlord found out that the tenant had not paid rent for three months, he filed for ejection to legally remove the tenant from the apartment.
• The security guard used ejection to remove the unruly fan from the stadium during the game.

The first example illustrates ejection as an expulsion by action of law. The landlord had the legal right to remove the tenant from the apartment due to non-payment of rent. The second example illustrates ejection as an expulsion by physical force. The security guard had to physically remove the fan from the stadium to maintain order and safety.
