-what does neglect friction mean ? i dont quite understand Answer by scott8148(6628) (Show Source):
You can put this solution on YOUR website! friction with the air (or any fluid) will act against the gravitational force that accelerates a falling object
___ this is why skydivers reach a "terminal velocity"; the force of atmospheric friction equals the force of gravity
