Mu-Friction

I think friction happens is because if there was no friction everything would continue to move forever.Friction is what stops a ball when you kick it. Friction acts as a resisting force between two surfaces.Also another surface is a bowling ally. There is not a lot of friction so you can easily fall. That is what friction is. 

Another Planet

I lived on earth the first decade of my life but i discovered this new planet named Guarla. The only difference is the gravity. This planet is twice as big as earth.Its harder to run to this planet. Also you have to have strong legs because the amount of gravity is a great deal more then earth.Also if you throw a ball, the ball will only go three feet unlike earth where the ball will go six feet. That is the difference on earth compared to Guarla.
