Final answer:
The described scenario where a person is pushed down and kicked viciously exemplifies Physical abuse, a form of intimate partner violence that can include psychological harm and emotional harm.
Step-by-step explanation:
The scenario "She pushes him down sideways then kicks his head viciously... he has become an it." exemplifies Physical abuse. This act involves inflicting physical harm with intent, which is one of the key components of intimate partner violence (IPV). IPV often comprises not just physical violence, but can also include emotional and psychological harm, such as eroding someone's self-worth or controlling their behavior. In the context of child behaviors, such actions might be classified as bullying, but in adult relationships, particularly those that are domestic, these acts are identified as abuse. The deliberate and violent nature of the act described in the question clearly points to an abusive situation, rather than self-defense, a verbal altercation, or mere intimidation.
