Is my dad physically and mentall abusing me!?

My dad and i were fine until my school called him for me not being in school cause i ditched. Which yes was dumb but i was stressing too hard and me and my friends went to the pool which was retarded. And he started yelling at me calling me a druggy and a addict even tho i only smoked weed and he found my pipe last year. I even quit smoking. I kept telling him that it was stupid but that triggered him even more and punched me in my ribs and slapped me in my face. And then he threw a chair at me and told me get out of the house. He said im a disgrace and that i am not his son and that he hates me and wishes that i could just disapear. Then after about an hour he cooled off and then told me if i ever go to school late even 5 minutes he would kick me out the house and he doesnt care if i sleep on the streets. Then the next day i was late to one of my classes and the school called again saying i was absent and he punched me twice in my ribs and slapped me in the face telling me to gtfo of the house now. but i stayed and tried to tell him that i wasnt absent but i was only a meer 5 mintutes late be he didnt care and now im banned for the whole summer break. he even threw my heavy school bag with alot of textbooks on my head full force and it hurt real bad. And as i packed my stuff to leave and be homeless he said why are you leaving to be with your druggy friends and said you either stay or leave. And if you leave and come back to the house you will be a dead body.so i stayd
