This is a picture of an ukulele, more specifically its strings. Each string has different amounts of tension applied to them, resulting in each string to have different sounds.
When thereʻs more tension, the wavelength is shorter, increasing the frequency. The opposite is true when decreasing the tension; the wavelength gets longer and the frequency decreases. The different sounds are produced by the tension applied in the four dials on the instrument.
My personal connection is that I tried to learn how to play this instrument multiple times because I had one that my aunty gave to me and I didnʻt want it to just sit and collect dust, but I never went past the beginner stage.

In this photo, The ball is at rest. However, it is about to be put into motion when I hit the ball with the bat.  Hitting a baseball requires a lot to do with physics and there are many different mechanics and forces that can determine how far the ball can go.
Trying to hit a spherical object with a cylindrical object isn't the easiest thing in the world. Luckily in this case, the ball is at rest. Therefore the only momentum and velocity it takes in this video comes from the momentum and velocity that I generate with the bat. Upon contact with the ball, the bat and ball both push against each other. The ball however accelerates in the direction that the bat hit it in (which is an unbalanced force) which case it (and luckily for my neighbors) the ball is quickly stopped and decelerates as it is caught by the net after it is hit.

This is an image of my hair straightener against my hair. As commonly known for its purpose, a hair straightener is used to straighten (and even curl) hair. When the object is on your hair, heat is transferred which then forms it into a different shape. This is also known as thermodynamics (heat as a form of energy which can transform to/from).
The extreme heat from the straightener causes the disulphide bonds to break. This breakage allows the keratin chains to move around slightly and assume a position that results in straightened hair. Along with straightening hair, it can also curl. When hair is passed through the iron while being held tight and straight, this object works by breaking down the positive hydrogen bonds found in the hair's cortex, which cause hair to open, bend and become curly. As too many heat can damage hair, this is a common device used in many places (households, salons, etc.).

This is an image of my microwave in my kitchen. Simply said the microwave heats things up but in a more broken down way, the microwave generates and sends short radio waves also known as microwaves around and these waves pass through the object all across the chamber of the machine. But even more broken down the microwave converts the electrical energy to the microwaves using a component called the magnetron which generates those short radio waves. The magnetron is also used in other things like in televisions where they would use these short radio waves and transmit it into a screen using some chemicals to create beams of light which would be the picture seen on the tv.

In this photo there is a basic electronic circuit displaying ohmʻs law. There is a lamp, a resistor, and a battery. When wired all together using this breadboard it creates a complete circuit and electrons will flow from the battery, through the resistor, through the lamp and then back into the battery. Also if you wanted to be more specific this particular circuit is a series circuit which is a path in which the whole current flows through each component. The reason I thought of using this for my photo is because I had actually learned about ohm's law, and resistors, and currency before this year, in Robotics, and this breadboard and a bunch of other things was the way to connect in robotics during the pandemic because we didnʻt have to prepare for a competition or anything.

This is an image of a human arm under an x-ray. X-rays could be used to detect bone fractures, abnormal masses, pneumonia, etc. X-rays are a form of electromagnetic wave. The high energy radiation is absorbed by the different densities of the body creating a shadow of the objects inside the body onto special film. The x-rays are absorbed at different rates in the body due to different densities and atomic numbers of the materials. Soft tissue cannot be seen in x-rays because it cannot absorb the energy from the x-ray causing it to pass through and expose the film underneath. Bones however, can be seen because it contains calcium which allows it to absorb the energy of x-rays. X-rays have wavelengths of 1ʻ 10^-11 m to 1ʻ 10^-8 m nanometers and are between ultraviolet radiation and gamma rays on the Light and Electromagnetic Spectrum. Excessive x-ray exposure could cause health problems such as increased risk of cancer.

This image shows a clear glass cup in front of my doorway, which has a stream of (mid-day) light flowing through. This light “wave” passes through the medium (cup), and as it passes through the medium, it bends the light (changing the velocity). The process of creating this picture was simply putting the cup in sunlight- no water needed- however, anyone hoping to get this effect might want to use a glass similar to mine; simply because of its shape which visibly reflects light better in comparison to say, plastic or tall glass cups. This process, results in a rainbow like effect, as shown in my photo. I personally haven’t seen any rainbows in the sky recently, so seeing that its possible to manipulate or “demonstrate” natural phenomenons with household items, makes you seem kind of like Mother Nature or a light bender (if there was one).

This image is of a steamer on a shirt. The steamer transferring to the shirt is a way of Thermodynamics. When the water is out into the steamer, it heats it u to create steam which is a source of energy which people also use as ways to power turbines and energy systems. They use the steam made form the heated water to transfer that steam energy onto clothes which relax and release tense fibers in the clothing t eliminate wrinkles and it shows also how when heat is applied things ease up and spread out. I would always wonder how this metal thing helped unwrinkle clothes and it was not until I learned more about physics through this class that I understood what is happening to allow for the unwrinkling of the clothing to happen.

This image is showing the water hose spraying mist and a rainbow appearing in the mist. This is called refraction. Refraction is when light changes direction when passing through one medium to another. White light contains the wavelengths of the entire visible spectrum. The white light from the sun bends through each water droplet and the light that goes through each water droplet comes out with a different color from the visible spectrum. This creates the rainbow we see. I chose to take this photo because I have seen this too many times but never really thought about the physics behind it. It sort of makes me think of when I would play with the hose when I was little and get sprayed with it when it was a hot day.

Explanation Paragraph:
During quarantine my dad built my sister and I a tetherball pole so we could go against each other. A key component to winning the game is strength and how hard or fast you can hit the ball, or the velocity of it all.
I relayed this to physics because the force in which you hit the ball will help you win or lose. If you use more force to hit it, it will wrap around faster and you will win. Hitting it hard also allows for a larger circumference of the ball moving in a circular motion. Depending on the force of the ball, the circular motion it goes in can vary and that can be good depending on what you want to do in the game. This also reminded me of physics because if you were to just swing the ball back and forth by the pole, it resembles a pendulum. There are other components relating to physics such as the length of the string and how it can vary how you play. Our game pole has a longer string which makes it easier for my younger sister to hit it but it also can be pulled further and is made of a sturdy medium (rope) that the ball won’t go flying off, that also has to do with velocity. The ball itself can also be relayed to physics like mass and how if the ball is deflated, it would be heavier and harder to wrap around the pole and hit because of its lack of shape and mass. While physics isn’t a must for playing tether ball, it’s definitely a plus.

In my photo is my beaded bracelet. I will be relating this picture to our physics lessons about refraction/reflection (light). These beads are spheres, when light rays hit the surface of the sphere some of that light is reflected, some is diffused throughout, and some light is refracted. This is all because the light ray will hit the sphere at one point will soon hit another portion of the sphere. We can see in the picture that light reflects and refracts throughout each bead differently and that is because the entry point of light in each bead it different, giving them different outcomes.
This bracelet in particular, is important to me because it was given to me by a loved one, which I where daily. For this reason I wanted to share this piece in this photo project. It helps to remind me to be thankful for the little things.

My image is of a nail gun. The physics phenomenon occurring in my photo is from our unit on forces. This specific image shows applied force. Applied force is, “a force applied to an object by a person or another object.” The equation for this force is F=ma. This equation proves that as long as a force is being applied, the object will accelerate. When the nail gun trigger is “pulled” a great force of air is pushed into the nail gun cylinder forcing a nail out. There are two examples of applied force in the photo. The first example could be both the finger pressing the nail gun trigger. The second example could be the pressurized air hammering out the nail. I chose this image because my family is currently working on renovating our house. Construction is something that I have grown up around. My family owns a construction company and watching them work together to accomplish this common goal is almost as equally rewarding as housing renovations!

My friends always like to talk about how there’s a lot of physics involved in skateboarding. I spend a lot of time at skateparks so I decided I might as well take a picture of someone doing an Ollie for my Physics Photo Contest Project.

To do an Ollie, the person on the board has to push the tail end of the board down with their back foot. This motion causes the board to bounce up off of the ground. This automatically makes me think of Newton’s Third Law, which states that every action has an equal and opposite reaction. The action of pushing the tail end of the board down has a reaction of the board bouncing up off of the ground.

Other laws involved would be Newton’s first law of motion that states an object will not change it’s motion unless acted upon by an external force. The skateboard isn’t in motion and remains on the ground until it is acted upon by an external force, being the person doing an Ollie.

Newton’s second law of motion states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to the mass of an object. In the case of doing an Ollie on a skateboard, the more force you apply to push down one end of the skateboard, the faster it will accelerate to bounce up. The more mass a board has, the slower it will be able to accelerate and complete an ollie.

There’s a whole lot more physics involved in doing just an Ollie and skateboarding in general, but this is just my quick summary!

For my project I took a photo of my remote control turning on the TV. The way that the tv is turned on is that the front end of a  remote control has a small light bulb. When you press a button on the remote, it sends out an infrared light signal to the TV. The TV detector on the TV then gets these signals and tells the TV what you want it to do, for example, to turn on or to switch stations.
I chose this photo because in todays society everyone uses their TV everyday, however no one, including me fully understands the physics behind how a remote control turns on the tv.
The process of taking this photo was that I was just sitting on my couch and I used the remote to turn on the tv. I held the lighted remote buttons to the tv and took a picture of the tv being turned on.

Elastic deformation happens when a force makes changes on an object temporarily. Inelastic deformation is when these forces that are applied changes the object permanently. In this photo, there are two balls of the same size, one made of clay and the other, a bouncy ball. Keeping the experiment controlled, they were both dropped from the same height on to the floor, therefore the same amount of force is being applied to them. The clay ball did not bounce due to the force showing its inelasticity and in contrast, once you let go of the bouncy ball, it stays in its original shape and bounces back up. I was inspired to do this playing with my dog because he has a couple of balls that canʻt bounce and some that can. While trying to see if he could catch some of the balls I was bouncing, I realized that some of them didnʻt bounce very high or at all. What I did was I took a video of me dropping the balls from the same height and took a screenshot of where it best showed the deformation.

For my project I took a picture of a boat floating on the water in a lake. The most important reason why a boat is able to float is the buoyant force. Buoyancy refers to the upward force exerted on an object that is in a fluid. An object's buoyancy depends on the relationship between the object's weight and the volume of the water it displaces. The upward force exerted on an object is equal to the volume of water it displaces. If the buoyant force is equal to or greater than the weight of the object, the object floats. I searched the internet and found out that this is known as Archimedes Principle. So basically, For a boat to float on water, enough of the boat's surface must make contact with the water to generate the proper force of buoyancy. If only a small part of the boat touches the water, the volume of displaced fluid won't be great enough to counteract the boat's weight and keep it afloat. It was difficult for me to decide on what to do since I wasn't at home, but I thought of the boat because since I am a surfer sometimes I go to some spots that I can only get to by boat. I was able to take this picture by having my family friends take the boat out so that I could take a picture of it out in the water.

The photo shown represents diffraction. When relating it to the mechanics it can fall under the mechanic of geometrical optics which is the behavior of light. Diffraction is when light waves encounter an obstacle or pass through an opening which leads them to bend. When looking at the DVD there are grooves or microscopic pits which make a parallel pattern as it carries information in the DVD. The pits are in rows that have the same width and they are equal distance to each other. The light passes through each microscopic pit and reflects along the aluminum plating creating the rainbow appear upon the DVD. The thought process that I had is that I wanted to do something light related just because it is going to be summer soon and I wanted it to be enlightening. I immediately thought of doing something related to geometrical optics which is the behavior of light or thermodynamics which when heat transforms to/from other forms of energy. Eventually I figured that I should do a rainbow and thought of taking a picture of oil when it is in a puddle but I never came across the chance to do so. Instead I remembered when I was younger and always wondered why there was a rainbow on DVD’s and CD’s. Therefore I had a personal connection behind the picture that I chose to take and I know that it relates to a lot of people because everyone sees it so often. https://drive.google.com/file/d/1SpesWA9Bhi8Yr87WDBV5g4BLeKB8HooD/view

For my project, I took a photo of my earbuds. The way I did this was I took my earbuds and hung it up, and took a pic. This is a form of Physics. This electricity and moving magnets which creates sound waves. When the earphones produce sound, it creates sound waves that bounce off your eardrums which your ear interprets as music. Also, when you plug your headphones into your devices, the magnet in your headphones creates an electromagnetic field which results in sound waves. My connection to this photo is that I am always listening to music, there is something about music that will always move me. Whenever I am in a bad mood, I put on my headphones and listen to music to cheer me up!  I did this project by myself by holding up my earbuds and taking a snapshot!

In this photo I have a piece of paper with arrows drawn in the same direction behind a glass of water filled only above the bottom arrow. It looks reversed because when the light passes from one medium into another (in this case the light is passing through the air, the glass, and water) the light can refract. Therefore, with the light refracted it makes the arrow appear in the other direction through the glass and water. Refraction is the change in direction of a wave, caused by the change in the waveʻs speed. As the light rays passed through the different mediums itʻs speed changed and itʻs angle of refraction changed. Itʻs angle of refraction reflected off the paper making the arrow appear backwards through the glass and water.

This image represents electricity. The outlet allows electricity to pass through the wires in order to light each bulb attached to it. These lights are in parallel. If one light were to burn out, it has no effect on the remaining lights, as they each continue to be in a closed circuit with the power source. This is the reason why if only one portion of the lights were to become defective, the others will remain functional. The inspiration of this specific image was the fact that I use this device everyday. I use it not only for a light source, but also for comfort as Iʻm a bit afraid of the dark, and it enhances the vibes. Itʻs a great representation of physics being used in our everyday lives, or at least in mines. Not only that, but I know a great amount of teens also use LED lights and can be educated on how this device is a form of physics.

My picture is of my Edison lights, where one bulb has gone out but the other lights continue to glow. In parallel circuits, components are connected together to one source in that it has multiple branches in which current flows through the circuit. In parallel circuits, the voltage remains constant for all the circuit branches, an element part of a circuit, and the current is split between each of the branches. This is different from a series circuit because the current stays constant while the voltage is split. Similarly to a building, each light bulb and the light switch is wired in a parallel circuit. This is so that when one lightbulb fuse burns out the rest remains operational and only that one branch has a broken current that is shut down. Parallel circuits in this sense are beneficial. I really love Christmas trees and Christmas lights because I am a December baby so I chose something with electricity. What was funny was my bulb went out a couple of days after the project was assigned… it was meant to be.

This image represents Refraction. Refraction can be defined as “the change in direction of a wave passing from one medium to another or from a gradual change in the medium”. This directly correlates to my image because the straw seems to have been “disconnected” or broken and isnʻt traveling in a straight line through the water. However, this is simply due to refraction. The angle of the straw is different, hence the image to us is different because the straw is passing through a different medium (water in a cup). This relates to me because you mustnʻt see things at face value, you have to be able to see things from a different pov. Also, things arenʻt always as they seem and sometimes it may be different than from what you were expecting. The process behind this photo was me filling up the cup with water and putting a straw in sideways. I then snapped the photo. https://drive.google.com/file/d/1Rud0TgS25ljM-l7k9UWqD8mxenwUyiy5/view?usp=sharing

(Please watch the introduction video in the link provided to see where the photo was taken.)
This photo shows droplets of water that have an initial diagonal velocity.  They move horizontally with a constant velocity due to the original inertia they are given.  The vertical velocity is slowed to a stop at the top of the parabolic path and then the droplets gain downward velocity due to the acceleration due to gravity.
There is a personal pilina (connection) to me with this photo.  It reminds me of my kuleana (role and responsibility) as a caretaker for the living things at my home be they people, dogs, cats or even the plants that need watering.  I had my friend Peter Grach help me take this video / photo to create the "Water Fountain Lab".  It was a simple process with him holding the hose and myself taking video footage with my phone.
