This weekend i played a soccer game at waipio soccer park in the afternoon. Are team lost the game but in the process I realized that a soccer ball undergoes both positive and negative acceleration. As i kicked the ball during a goal kick it went from a velocity of zero to around 30 mph by the time it left my foot resulting in a very high acceleration. But, as soon as the ball left my foot at 30 mph it immediately began slowing down as it rolled across the grace. It traveled around 50 yards before coming to a complete stop. This decrease in velocity is an example of negative acceleration. To bad this physics epiphany did not help us win the game.

chris, that is such a terrific example of physics in soccer, wow 30 mph, that sure is fast
Lol is it weird that my homework has to do with soccer players kicking a ball & how it accelerates? Haha
