Unfortunately I have to agree with Log (that’s not what it sound like Log) on this one. For one thing there are not examples in real life of the Textbook zombie. And even though there are legends across the world of re-animated corpses walking the earth, they’re all so radically different from each other to not give a good solid example.
But I will say since you asked a basic question that has a well established answer in common modern zombie mythology, I will be able to give you an answer.
“ The best way to stop a zombie is trauma to the brain.” So hit them hard in the head.
“ Burn them.” This is another idea, but it is more risky. The zombie may take time to fully burn to the point it will be unable to remain mobile. Now you have a walking fire that’s heading toward you.
I would also say if you can’t hit their head, attack their legs. This won’t stop them, but it will slow them down.
