This is a picture of our lab that involves the relationship between force, mass, and acceleration. For this lab, we have to see how a carts mass affects the force of its movement and vice versa. This lab will not only show how force, mass, and acceleration are related, but how these forces can be applied into real life. For example, instead of measuring how much force of a 100g cart can create, we can measure how much force a bullet train makes. With using these same principles and applying them to real life situations, we can find out the "hows" and "whys" about our planet.

This is a picture of an arrow. This arrow is a vector. A vector is a quantity of magnitude and direction. I chose an arrow to represent a vector because it's the most basic form of a vector. There are many vectors that surround us daily. Cars, planes, bikes are few examples of the vectors on earth. Vectors are important because they relate to acceleration and velocity. Anything that moves has acceleration and velocity. In class we have been studying how certain vectors can have the same length, but different direction. Also, we have been studying how three vectors can create a triangle.

This is a picture of an accelerating Porsche. Like many of our P.A. problems, the Porsche’s acceleration and velocity are quite fast. If we wanted to find how fast the Porsche would go in a certain distance or time, we would use the D=1/2at²+V_ot, or d.a.t. equation. By using this equation, you can find the distance, acceleration, or time. This equation is not limited to objects that only move on the road, but falling and rising objects. There are other equations that are used to find velocity, acceleration, and time. This equation will help us find the velocity of our next lab, the falling ball lab.

This is a picture of position vs. time graph. I chose this picture because we are learning about how objects increase their distance over a period of time. This graph relates to the Olympics lab. As each “runner” ran, hopped, and sprinted, their distance increased as time increased. Each “run” had a different distance covered in a certain time, thus creating different slopes. The slope of the sprint was much steeper than the slope of the hop. This graph also relates to the acceleration and velocity of the moving object. As the object covers more distance in less time, the acceleration increases.

This is a picture of someone playing a guitar. I chose this picture because it shows how vibrations of string can produce sound. Depending on how fast or slow the guitarist strums and where he decides to press his fingers on the frets, he is able to control the tempo and musical notes of the guitar. This picture also shows how a strum is much like a period of a pendulum. When the guitarist plays short periods, he plays a faster tempo, and vice versa; if the guitarist plays a slower period, he plays a slower tempo. Also, this picture can relate to myself because I enjoy playing guitar too.

This is a picture of a golfer swinging their club. This relates to our physics unit because the golfer has to accelerate the club and hit the golf ball. Much like the pendulum, the golf club and the golfer's hands represent the string of the pendulum. If the golfer wants to hit the ball with less force, his period or backswing is shorter. If the golfer wants to hit the ball with more force, his period or backswing will be longer. This picture can represent how wind can affect the flight of the ball. Much like the string and weight of the pendulum, after the golf ball is hit, the wind may affect the flight of the ball.

Letter of Introduction:

My name is Joseph Yokoi. I’m Hawaiian, Japanese, Chinese, Korean, and Portuguese. I’m finally a senior at Kamehameha, and I’m proud to say that I enjoyed being at Kamehameha for 12 years. I’ve played for the Kamehameha Baseball since 7^th and hopefully we’ll end this year’s baseball season with a bang.

Science has been one of my favored classes mainly because of the neat labs we’ve done in Biology and Chemistry. As for physics, I’m looking forward to learning are the “how’s and why’s” about everyday life. How does gravity affect the bounce on a ball? Why does heat rise up and not down? I’m excited to learn about the reasons why things happen.

Math has been another favored class of mine, and currently I’m in Pre-Calculus.
