This weekend I went with my older brother and his family to the ‘Iolani v. Kaimuki state football game. In physics we learned about impulse and momentum. We learned that momentum equals mass times velocity. When the football is thrown, it has a lot of momentum because it has a large velocity. We also learned that impulse is equal to the change in momentum or force times time. When receivers, such as Josiah, try to catch the ball, they try to have “soft hands” and increase the amount of time it takes to catch the ball so that they can reduce the amount of force exerted on them by the ball. Also, when our awesome defense tackles the other team, they tend to have a larger momentum than the other players. When this happens there is usually a stick collision and the defensive player will force the offensive player into the ground or in the other direction. Go Raiders!
