What I learned This Semester

I have learned a lot this semester in Physics. I have learned about the different ways an object can be weighed and measured. I have also learned how mass is relative to speed. I learned how to find the velocity of an object using equations. I also learned how to find the acceleration, distance, time, and speed of an object. I have learned about two-dimensional kinematics as well. I have learned how to solve for two different dimensions using equations like, Dy = 1/2 AyT(squared) + VoyT. I learned about Newtons laws. I learned that gravity is an acceleration and that weight is a force. I also learned about all of the things that oppose forces in the opposite direction. Examples are friction and another force pulling the object in an opposite direction. I have also learned about momentum and I learned that momentum is conserved. If a moving object was to crash into a stationary object, the object would be transferred from the moving object to the still object. Finally, the last thing that I have learned this semester was energy. I learned that energy is also conserved. Work is any change in energy. I also learned how to find power. This is what I have learned this first semester, and I have another semester of learning of physics, super fun! ....

This is me at one of my soccer games. I am in the blue and the opponent is in the yellow. As you can see here, I am pushing the defender away from me so that he does not get near the ball. I am also doing work as well. My arm is pushing toward an opposing force that wants to go in the opposite direction. This is type of work is energy. The type of energy that is being produced starts off at kinetic energy because we are both moving, then goes to spring potential energy because I am pushing back on him, and then it goes back to kinetic energy because we are both moving again after this. 

I got this egg from my refrigerator. It looks all shiny and nice, I want to eat it. The reason why I have a picture with this egg is because it has to do with my egg drop project that I did with Jenai. We had a first design of a pyramid sort of thing made out of cardboard in which the egg would go on the top and we would put cushion and weight on the bottom so that the device would land standing up, but we depleted that idea. The way that we made our egg drop project is that we took a shoe box for our outer protection and frame. Next, we put a bag of coins in it so that it would be weighted down and land flat on its bottom and not be affected by wind on its descent down. We put cotton and a air bead pillow over the coins to prevent the egg and coins from hitting each other. Finally, we wrapped the egg in a sock for extra protection. 

K.O.

This is my boxing glove. It is not an ordinary boxing glove though, it is a Captain America boxing glove with a huge mass that comes along with it! If I were to swing a punch at someone while I had these boxing gloves on, it would do some serious damage to the person that is getting hit. The reason for this is because the more mass that an object has, the greater momentum it has, increasing the impact of the punch. If I were to punch someone with a regular glove, it would not hurt as much because it does not weigh as much as the awesome Captain America glove. Also, if the person I was punching was going with the direction of my punch, it would not inflict as much damage because going with the punch will increase the time of impact and the more time an impact has the less force that it has. 

My awesome 4 wheel sports car hit my wooden semi-truck and the two of them collided. Luckily the two vehicles had no damage on them. The semi-truck was at rest while the sports car was traveling at a high speed toward the semi-truck. When the two vehicles collided, the sports car stopped and transferred the momentum to the semi-truck, pushing the semi truck forward. The two trucks should be going at around the same velocity because the momentum in equals the momentum out, or Pin = Pout. If the two were heading at each other at the same velocity, two would bounce off of each other and travel backwards in the opposite direction. 

Momentum

This is my toy car that I rolled across my floor. The unit that we are now starting for our physics class is on momentum. I think that momentum is the force of the mass and velocity that something is going. For example, if someone was driving their car at 120 miles per hour and then tried to stop instantaneously, it would not happen because the car would have too much momentum. The car would have too much mass going at a high velocity, therefore making it impossible for the car to stop instantaneously. The formula for momentum is "Momentum = mass x velocity"

Newtons Second Law

Some people deserve a hi-five... in the face... with a chair. No, but really here I am performing a prime example of Newtons Law. I am trying to push my chair into my desk but it is not moving. Reasons for why my chair is not moving is because my arms are at a high angle, which would make it harder to push forwards. Also, the mass of the chair contributes to why I cannot push in my chair. The friction from my carpet in my room is also another factor that makes it difficult for me to push in my chair. If I were to have a wooden floor in my room I would be able to push in my chair a lot easier because there is less friction on wooden floors. If I push my chair with enough force, my chair will push back in. 

This is the lei that I got from senior lu'au last night. My lei is purple, which is the best color to use for a lei. I used my lei to demonstrate forces acting upon my lei. The door knob is exerting an equal amount of force as my pull on the lei in opposite directions, which is why the lei is evenly flat and not sagging downward. Also, another force acting upon the lei are the milligrams which cause a downward force. If I was to move the lei around with my hand around the door knob, the lei would produce force friction towards the knob. If I took the lei off the knob and put it on my desk, then inertia, mg downward force, and normal force would be acting upon my lei. 

Fig Newtons

Here I am in Midkiff with my bag for school. This is my most favorite bag that i have ever had. I got this backpack from the vans store in Florida. My bag is not in motion. The reason why my back pack is not in motion is because of inertia. My bag wants to stay where it is and does not want to move. Another reason why it is not moving is because it is at the center of mass. The table is flat, and the surface area is also bigger than the surface area of my back pack, causing to stay where it currently is. 

G-G-G-G-GOOOOOOOOOAAAAALLLLLL!

This is me playing soccer. Soccer is my passion, and is my most favorite sport of all time. Here I two defenders are approaching me as I am kicking the ball and crossing it across the field to one of my teammates making a run. By the way I got an assist on this play.. just saying. Anyways, the unit that we are currently learning about are about vectors, which deals with direction and magnitude. Here after i kick the ball, the ball will travel with a direct speed and magnitude to one of my teammates across the field. If I had the dimensions, I would be able to figure out the vector of the ball by using the correct vector equation. 

East Side

This is a napkin with a compass drawn on top of it. The compass has the directions on it. The directions on a compass are Nortrh, South, East, and West. Also on a compass, they have degree angles to show whoever is viewing it where their exact location is. People often use compass' to find out where they are and where they are going. A common example of this is when people go camping. A compass is often taken so that no one gets lost on the trip. This can relate to what a vectors. When dealing with vectors direction is one part of the process. There is a degree measure for each direction (North, South, East, & West). 

Waterbottle got some Wings

Here, I have taken a normal bottle of Dasani water and threw it up into the air. What has been exemplified here is kinematics. Using the systems of equations that kinematics has to offer, I can figure out the velocity at which the bottle is traveling. I can determine how long it will take the bottle to reach the ground using an equation. Acceleration and distance from which the bottle was thrown can also be determined using one of the many equations in kinematics. Everything that is thrown into the air has the same motion; fast, slow, stop, slow, fast. So as my bottle is thrown into the air, it goes fast, slows down, then stops at the highest peak, then slowly comes back down, and then goes faster and faster. 

BLOGPOST #5 Drop it low

This is a drop of water. This may seem like just a drop of water, but this drop of water has to do with Kinematics. This has to do with Kinematics because from the drop of water, you can figure out the velocity of the drop of water. You can also figure out the acceleration of the drop of water from when it comes out of the faucet to when it hits the bottom of the sink. The initial velocity of the drop of water is zero because it starts form rest. You can also figure out the speed of the drop of water by finding out how many centimeters the drop of water moved per second until it impacts the sink. 

This is a really nice car. OOps, my mistake, its a van. The van is traveling at a speed of 20 miles per hour.. or I hope it is because if its going any faster, it will be speeding and breaking the law. Speed is a big factor in Kinematics. If an object is thrown up in the air and caught at the same point at which the object is thrown, then the speed will stay the same throughout. By finding out the time and the initial velocity of a car, you can find out the acceleration and the velocity of a car when it was traveling. 

Slow down buddy boy

This here is a Speed Limit Sign. The speed limit for my street is 20 mph. (mph) is short for "miles per hour". The reason why this has to do with our unit is because we are talking about speed, and miles per hour has to do with the speed of an object. Speed is defined as the total distance traveled per unit of time. The reason why they call it "miles per hour" is because it is the number of miles an object can travel in one hour. Speed has has to deal with this unit because it is related to distance, vectors, and scalars. Mph is a measurement to show you the distance that can be traveled in miles for every hour. Speed also deals with vectors and scalars because it deals with direction and magnitude. Speed is important because it is used in everyday life. 

Blogpost #1 (About Unit)

Here we have a ruler. This ruler has to do with what were doing because it has to do with measurements, and measurements are a part of the system of units. A ruler is one foot long. Each foot has twelve inches.  Three feet equal one yard. So, a yard would have thirty six inches total. I happen to be sixty six and a half inches, which is five feet and six and a half inches. I think that its weird that we use the foot while almost the entire rest of the world uses the meter. But hey, thats just me. The foot is still a pretty good standard of measurement though.

My name is Kā'eo Paik, and I am currently a senior at Kamehameha. I love to play soccer and it is my favorite sport. I play for outside leagues as well as for school. My favorite color is blue. I have three older siblings, all of which are girls. I am an uncle of 6 children soon to be 7. Freshman year, I took physical science at another school and I did excellent getting an A. I didn't take science sophomore year but I took biology my junior year, and I did a little bit above an average job in that class. I Got an average of a B in that class. Now I am currently taking chemistry. The math course that I am currently in is discrete math. In completing this course, I am hoping to learn some of the many laws of physics to strengthen my scientific knowledge. I am also hoping to get an A in this class. 

The story behind my picture is simple. First off, as you know from above, I love to play soccer. It is my life and my passion. This picture also describes me because I like to dream big. Just as the title of this movie, I dream, and hope to make my dreams become a reality and become someone that is very successful in the world when I become older. This is also one of my favorite movies.
