A more thorough explanation:

Definition: Effected by force or threat of force against opposition or resistance.

For example, in the law of trespass, the term "forcible" is used to describe any act of physical interference with the person or property of another. This includes laying a finger on someone without lawful justification, walking across someone's land without permission, or breaking into someone's house with force. All of these actions are considered forcible and can be considered a trespass.

Another example of a forcible act is when someone uses threats or force to make someone else do something against their will. This could include physical violence, intimidation, or coercion.

Overall, the term "forcible" refers to any action that is done with force or the threat of force, and is often used in legal contexts to describe acts of violence or trespassing.
