Until you become an adult or become emancipated, you are considerd incompetent by the courts as a result of your age. You need to discuss these matters with your mother who is responsible to take steps to protect you.
If you are abused, hit, assaulted when you are with your father, you should have a plan with your mother as to steps to be taken, such as calling 911.
I would suggest that your mother contact a family law attorney and get a 30 minute free consultation. it is important that she take steps NOW.

Your mother can file a petition to terminate his visitation rights or to ask that his visitation be supervised based on his abusive behavior. Your mother will need to go see an attorney to start that process. If your mother is unwilling or unable to do this, then you may want to discuss the issue with your school counselor. Depending on the circumstances, the school counselor may make a report to the police for them to investigate the abuse.
If you are ever in a situation where you are being physically abused, call 911 right away.
Good luck to you.
