For XC practice last week, we ran to Kapiolani park to play ultimate Frisbee.  While playing, I noticed that at the tennis courts nearby, the players were hitting the ball with their racket.  I also noticed that the  soccer ball was being kicked by the soccer players on the nearby soccer field.  At this moment, I recalled that when the soccer ball is kicked it is like a vector.  Its horizontal velocity was constant throughout it's flight while its vertical velocity made a parabola.  It had a negative acceleration of 9.8 meter per second squared and its vertical velocity, therefore, was decreasing in speed on the way up and increasing in speed on the way down.  At the top of its altitude, or maximum height, its vertical velocity is 0.  This soccer ball reminded me of a great soccer game between Iolani and Millilani for the state finals which took place last year.
