Physical violence is an act attempting to or resulting in pain and/or physical injury. It includes beating, burning, kicking, punching, biting, maiming, the use of objects or weapons, or tearing out hair. At its most extreme, physical violence may lead to femicide, or the gender-based killing of a woman. Some classifications also include trafficking and slavery in the category of physical violence because initial coercion is often experienced, and the young women and men involved end up becoming victims of further violence as a result of their enslavement.
