Cation-exchange chromatography is used when the molecule of interest is positively charged on the neutral pH. The stationary phase is than negatively charged and positively charged molecules are loaded to be attracted to it. So, positively charged peptides will elute the last.

Newton's First law of motion: An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
This is also known as the law of inertia
