Solar car travels more than 12,500 miles to break world distance record

Mass is mass! Force is force! Rolling resistance should be described as the horizontal force it takes to move a wheel that is under a vertical force. N as in Newton is force. g as in gram is mass and the force that a mass creates depends on where in the universe we are. Yes, we are on the Earth. But mass and force is still not the same.
