American footballs and Rugby balls are both considered 'balls' but neither are spheres.
there are bowling balls, footballs, rugby balls, bouncy balls (the balls connected to the dick), volley balls, beach balls and exercise balls
All types of footballs roll, as they have curved surfaces. Some footballs (soccer) are nearly spherical and will roll for greater distances. Rugby and Australian footballs are rounder and will roll farther than the tapered US footballs. Even the US and Canadian balls can roll for dozens of meters (yards) under the proper circumstances.
a football or any type of ball ========================= Any kind of ball with a ballular shape. The [American] football is not one of them.
They are larger than American footballs, but not quite as large as rugby balls.The Wikipedian article on the topic of footballs states:"A regulation [Australian] football is 720-730 mm (28-29 in) in circumference, and 545-555 mm (21.5-21.9 in) transverse circumference, and inflated to a pressure of 62-76 kPa (9.0-11.0 psi). In the Australian_Football_League, the balls are red for day matches and yellow for night matches"
I think elliptical galaxies are the galaxies you are referring to. Scientist normally describe them as a flatted disk shape. These galaxies contain mainly older stars.
Australian Rugby Championship was created in 2006.
Australian Rugby Shield was created in 2000.
Rugby balls are similar to a football in shape, but are slightly wider and bigger.
SO that it would be easier to bounce off the ground. if it's square or triangle, it would be hard to bounce if off the ground.. you could try it by yourself if you don't trust me...
Yes. There are lots of types of football. American football, Rugby and Australian Rules Football all use oval balls. Soccer and Gaelic Football use round balls.
