Static Equilibrium

For my physics blog this week, I took a picture of cars moving on the freeway when I was going out to the Waipio soccer field. Although it’s not a perfect example of this vocabulary world, I feel that in this picture it could resemble “static equilibrium.” Static equilibrium means that it’s a stationary object that’s not accelerating. In this picture basically all the cars are going about 55-60 mph (which is the speed limit.) This means that for the whole stretch of the freeway, the cars are basically in static equilibrium, especially because of the fact that there’s no traffic at this time. 

UH Gameeeeee

            The picture that I chose this time was one of a UH fan running in a referee fat suit holding two pumpkins during a relay race they had during half time. This picture relates to what we’re learning in physics because it’s an example of Newton’s Second Law of Motion, which the acceleration of an object is inversely proportional to the mass of the object. As you can see, the runner is wearing an oversized costume while holding two large pumpkins that makes their usual mass increase. That’s why during the relay both of the competitors weren’t running as fast as they probably could because of the increased mass. 

Force and Motion

My picture shows the Kamehameha football playing against Punahou this past Saturday at Aloha Stadium. This was only one of the many plays that led our Warriors to victory against the Puns! Yay! Well, anyways this picture shows an example of what we’re learning in physics, which is force and motion. This picture is an example of Newton’s Third Law of Motion, “The Law of Action Reaction” which states for every action, there is an equal and opposite reaction. For every Kamehameha football player that went up against their Punahou opponent, the Punahou players would in return go up against Kamehameha to try and stop them. This picture shows two football players, one Kamehameha and one Punahou, trying to stop each other from getting to their destination, therefore creating an equal and opposite reaction against one another. 

Simple Vector

My blog shows a picture of a vector that I drew on my physics folder. This shows an example of a vector since of course, it’s an arrow and it has both magnitude and direction. This vector is pointing in the northwest direction, meaning if you break it up (bureku) it will be so many degrees north of west. Meaning, it will be that many degrees north of the x-axis on the west side. I’ve learned that different vectors have different magnitudes depending on the size of it and what direction it’s headed in. Vectors aren’t always arrows though; they could be flags on the flagpoles, cones on the road or even a car. All of these things have a certain magnitude (speed) and are going or directing things in a specific direction. 

Sad Loss

The picture that I took is of the football goal posts at the Aloha Stadium. I think that these show vectors because they both have magnitude and are indicating a certain direction. For example, the football has to go through these goals posts in order for the team to score a point. An example of this would be the Kamehameha vs. Punahou game this Saturday. All Kamehameha needed to win was a field goal of three points, but we weren’t able to do that. The goal posts have a direction pointing upwards even though the ball has to go through the posts. Their direction is also upwards even though there aren’t any arrows to indicate it.
