After being subjected to both in my past, I'll take physical over emotional any day. Physical abuse will attack your innocence as well, but nothing is quite as intimate as raw emotional abuse.
Abuse, by the way, is what happens when you are harming a particular person who implicitly and explicitly trusts you to a fault to the point where you are leaving lasting harm on the target. Abuse can be actual physical beating leaving injuries[footnote]A light cuff upside the head doesn't harm the target, but it does get their attention[/footnote], forcing a child to handle themselves when you're gone for an extended period, usually measured in days, repeated and intentionally invoked psychological trauma, usually leaving lasting results, and repeated attacks against a child's confidence and innocence.
Often, a person who's been subjected to abuse will not have a "childhood" in the sense that others have. Rather, they're forced to grow up earlier in life, creating an equally scarred and mature person in their adult life. Abuse can affect a person in multiple ways, two of which being repeating it with their own family as they grow or choosing to help those who were in situations like theirs or worse.
