Blog 14: Refraction

I was looking at my friends pictures when I noticed this particular photo and I immediately thought of physics when I closely examined the picture. Light from an outside force reflects off the water and since the water has ripples the water bounces off in all different directions. It bounces off each ripple the same angle that it hits the wave. Also, the lights underneath the water aren't exactly where your eyes perceive them because light gets refracted from water to air because it takes the path of least time and since light travels slower in water than air, it refracts.

Blog 13: dogs

When I first saw this picture I didn't think much of it but then I realized that this is probably how a dog would see us because dogs are completely color blind. A lot of males are color blind as well but they still see color, they just have trouble seeing certain colors and the cannot differentiate some colors. On the other hand, dogs cannot see color. Unlike humans that have both rods and cones in their eyes dogs only have rods. No cones means no color.

Blog 12

As I was looking back at pictures from the 'Iolani Family Fair, I noticed this picture because the bright colors seemed to jump off the page. The first thing that you see when you look at this picture are our shirts and the bottle caps of the middle group of bottles. That is because that shade of bright green/yellow are perceived strongest by your eyes which makes them easy to spot. Also, when one looks at this picture there are many colors, but ur brain only actually perceives three main colors, red green and blue and it is the mixture of these three that makes different colors.

Blog 11: Family Fair

When I looked at my pictures this weekend, I noticed all the pictures that I had of the Iolani Family Fair that took place a couple of weeks ago. There was non-stop physics taking place the entire time at the fair. One thing in particular stood out. One of the rides that we have is "The Whirly Bird" in which 4 riders rotate around a center axis. I remember when I used to ride it, it would feel like I was getting pushed to one side and now I know that that is because of centripital and centrifugal forces. If the seats were to dissapear I would be flung outward and a line tangent to the circle the ride is making.

Blog 9: Flash

Before when I used to look at this picture i would just think, whoa, that flash is pretty bright, but now due to physics, I can finally understand why it is so bright. In most cameras, there is a capacitor which is used for the flash. It stores energy and then unleashes it all at one time and in this picture, I was caught by surprise when the camera's flash was so close to my face and I had to lean back because of its immense brightness. A capacitor is defined by two formulas, C=Q/V and C=kE(electric constant)A/D.

Blog 8: Rotational momentum and Impulse

As I was looking through my old pictures, I noticed this picture of my volleyball team. It reminded me of how while playing volleyball, there is physics going on all around. For example, when a player hits the ball and puts spin on it, it has rotational momentum and when you pass a ball, there is an impulse between the ball and your arms. You do not want the force to be too big so you increase the time between contact because J=Ft.
