Why doesn't a ball roll on forever after being kicked at a soccer game

The ball has to push things out of its way in order to keep going.
For example:

-- billions of air molecules
-- hundreds of blades of grass .

-- To push something out of its way, the ball exerts a force against the
obstacle, and pushes it some distance. 

-- A force acting through a distance is 'work', and that means 'energy'. 

-- The ball has a certain amount of energy ... the amount you gave it
when you kicked it.  It gives every air molecule and blade of grass a
little bit of energy, so the ball has less and less as it goes along. 

-- Eventually, it has no more energy to use to push things out of the way. 
No energy means no motion, so it stops. 

-- If it were in space where there are no air molecules and no grass,
it would go on forever. 

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
