What are the differences between the 4 types of abuse

Physical
Mental
Neglect
And Sexual abuse.
Physically is laying a hand on the child, or hurting them using excessive force.
Mental is using tricks like," If you don't get me my drink, I'll hurt you later." Which kind've qualifies as mental and physical if they actually go through with it. Or another example would be," I'll leave you at a bus station (or some place else) if you don't do this." It's fear evoking to get something done your way.
Neglect, would be not feeding them or giving them the attention or nutrients a growing child or teen or anyone really would need.
And finally sexual. Sexual abuse is forcing someone into something to get their way, or making someone do something they're not ready for - or even nonconsensual which is especially illegal if they're underage. There are plenty examples of that.
