Cargo [ˈkɑːɡəʊ / ˈkɑɹɡoʊ] refers to freight carried by a ship, aircraft or motor vehicle. It comes from Spanish cargo (charge, burden, position, post), from cargar (to load, carry, charge), from Late Latin carricāre, from carricō (to load), from carrus (wagon, a two-wheeled baggage cart, load, two-wheeled Celtic war chariot), from Gaulish *karros (wagon), from Proto-Celtic *karros (wagon), from Proto-Indo-European *ḱr̥sós (vehicle), from *ḱers- (to run) [source].
A car [kɑː / kɑɹ] is a wheeled vehicle that moves independently, with at least three wheels, powered mechanically, steered by a driver and mostly for personal transportation; or any vehicle designed to run on rails [other meanings are available].
It comes from Middle English carre (cart, wagon), from Anglo-Norman carre (cart), from Latin carra, from carrus (wagon(load), cart(load), load), etc. – so the same roots as cargo [source].
