The bible says that disciplining children is necessary for them to grow on the right path. However, some people think that physical discipline is a form of abuse.

If the use of physical means to discipline your child is taken too far, then yes it is a sin and a form of abuse that might not be helpful.
No
Proverbs 29:17 has this to say to parents: “Discipline your child and he/she will give you rest; he/she will give you delight to your heart.” A Scripture, from Proverbs 13:24, reads thusly: “He who spares the rod hates his son, but he who loves him is careful to discipline him.”
