A more thorough explanation:

Physical force refers to power, violence, or pressure directed against a person or thing. It can be used to gain control or prevent resistance. There are different types of physical force:

Force consisting of a physical act, especially a violent act directed against a robbery victim. For example, hitting someone with a bat during a robbery.

Threats and intimidation to gain control or prevent resistance, especially threatening words or gestures directed against a robbery victim. For example, pointing a gun at someone during a robbery.

Violent action known to create a substantial risk of causing death or serious bodily harm. A person may use deadly force in self-defense only if retaliating against another's deadly force. For example, shooting someone who is trying to kill you.

Unreasonable or unnecessary force under the circumstances. For example, using a taser on someone who is already restrained.

Force that is not excessive and that is appropriate for protecting oneself or one's property. The use of reasonable force will not render a person criminally or tortiously liable. For example, using pepper spray on someone who is attacking you.

Force that is directed against a person without that person's consent, and that is a criminal offense or an actionable tort. For example, punching someone without their consent.

Overall, physical force is any type of power, violence, or pressure used against a person or thing. The different types of physical force depend on the circumstances and the level of harm caused. It is important to use reasonable force and avoid excessive force to avoid criminal or tortious liability.
