Australian football and rugby are both popular sports in Australia, but they have key differences in rules, gameplay, and scoring. Australian football is played with an oval-shaped ball and involves kicking and handballing to move the ball down the field. Rugby, on the other hand, is played with a more oval-shaped ball and involves passing and running to advance the ball. Additionally, Australian football has a larger field and more players on each team compared to rugby. Scoring in Australian football involves kicking the ball between goalposts, while rugby scoring is based on scoring tries and kicking conversions.
Because football is its original name, as the ball is kicked by the foot. It is called football around the vast majority of the world, it is only in America where 'American Football' is so popular it is called soccer. Soccer is sometimes used in Australia due to Australian Rules Football. Both American and Australian Rules football are variations of soccer (football) hence there names.
Football is one word, and can refer to soccer, or US football, or Canadian football, or Australian rules (footy), or generically to a ball, round or oblong, used in various games including soccer, football, and rugby.
