Both (and don't forget sexual which is a form of physical but slightly different) are horrendous and cause damage...but I would say that mental (and/or emotional) is because the scars are deeper and never completely heal (and in physical abuse the body can be damaged and heal but it also leaves mental/emotional scars and damage that never completely does).

All three forms of abuse are emotional abuse, and regardless of the injury emotional wounds may or may not heal. );

I've never seen physical abuse that hasn't been accompanied by mental abuse.

Both are equally harmful.

Tough call mental would stick with ya longer those wounds are harder to heal but physical would turn into mental eventually

I can't imagine a scenario where physical abuse doesn't include mental abuse outside of random or inadvertent assault.

You left one out

i don't think it works that way.

both are incredibly painful.

Both take there toll

Mentally

Depends on the person, some have a thick sin and met things roll off.
