Why does a proton slow down as it movies into higher potential?

Homework Statement

No real problem statement, just a question.

I was reading through my textbook and found this statement: "A positive charge slows down as it moves into a region of higher, more positive potential."

I spend some time thinking about it and I can't figure out why... does more positive potential act kind of like a positive charge or something? Can anyone help?

If you push a positive charge toward a Positive potential will it repel or attract? If it repels you have to do positive work.

If you have to do positive work, then imagine what a particle with kinetic energy is going to do. Slow down since the force it faces is against it.
