What term describes the use of threats to compel someone to act?

The term that describes the use of threats to compel someone to act is "coercion." Coercion involves forcing an individual to take a certain action against their will by using intimidation, threats, or pressure. This legal concept is crucial in understanding various areas of law, including contract law and criminal law, where the presence of coercion can render consent invalid or lead to criminal charges, such as extortion.

In contrast, other terms listed do not relate to the act of forcing someone through threats. "Consent" refers to the voluntary agreement to engage in an action or accept a situation, which is the opposite of coercion. "Composure" relates to maintaining calmness and self-control, while "collaboration" involves working together willingly towards a common goal, devoid of threats or intimidation. Understanding these distinctions is essential for recognizing the implications of actions based on coercion in legal contexts.
