7) Start off the Season

     On this past Saturday morning the 'Iolani Paddling program had their first race of the season. Now, paddling is not an easy sport. There is a lot of practice and dedication from each individual for a crew to succeed. Although I was not able to race yesterday, I was happy to support my team and am sure I will be given the chance to paddle in the next race.
     Since I had to leave early for a baptismal service for my cousin and a baby shower, I do not know who won for the girls’ races. On the other hand, I know the boys did their very best.  As I was watching the girls paddle out to the starting point, I recalled that energy and force is necessary for the canoe to glide forward. Similar to Newton's Third Law: For every action there is an equal and opposite reaction. In this case, the paddle is pulling the water backward as the water pulls the canoe forward. Here are some photos of the girls paddling out to the starting line.

5) Wishy Washy Centripetal Forces

     This Sunday morning I woke up to discover that my pile of clothes were starting to pile up more and more as the clothes in my drawers were becoming less and less.  Some people believe that washing clothes is a hassle and I am not going to lie. Washing clothes is a very tedious and time consuming job, but hey you need clothes so you have to do what you gotta do! hahaha Well, I decided to wash my clothes before school starts.  So, I began to separate my clothes into different piles/loads:  whites, jeans and blouses.  I  went downstairs, loaded the washer with my clothes, soap and water. As my clothes were in the washer my grandma made breakfast downstairs.  As I was eating, I realized that I needed to do a physics blog.  It struck me that washing clothes is a great example of centripetal force.  First of all, centripetal force is any force that makes an object move in a circular path.  The centripetal force always points toward the center of the circle.  In this case the water in the washing machine is moving in a circular motion.  However, if the centripetal force is removed from the motion, then the object reacts by continuing in a tangent direction from the center of the circle.  Therefore, when the centripetal force is removed from the washing machine the water will travel tangent from the circular motion of the washer.  Here are some photos of my family's washing machine:

6) Projectile Motion & Water Guns

     This past Sunday afternoon my younger brothers and cousins were playing outside in the yard.  My younger brothers and cousins were having a water gun fight.  After the water gun fight I told my brother, Daysen to aim the water gun in the air and shoot water into the sky so I could take a picture of the projectile motion of the water.  However, the water ended up all over my younger brother Nilasoni, and my two cousins Issac and Keoni on the swing set.  That was such a cute and funny moment.  In physics class we learned projectile motion earlier in the course.  On the other hand, a brief reminder of projectile motion is the movement determined by an object's initial velocity and the constant acceleration of gravity.  In this case, the movement of the water is determined by the initial velocity of the water exiting the water gun and the constant acceleration of gravity.
