Shocking Circuits

This picture shows a series circuit. In this circuit the voltage of all the light bulbs is equal to the voltage in the batteries.The voltage in each light bulb is a third of the entire voltage, because the resistance in each of light bulbs are the same, because there are three places where the voltage needs to go. The current in this circuit is the same because the circuit is in a loop, the electrons don't have any where else to go so the current is the same throughout the entire series circuit.

This picture shows a parallel circuit. In this circuit the voltage of the light bulbs are equal, because in a parallel circuit the voltage of each light bulb is equal to the voltage that the batteries produce. In other words the voltage of one of the light bulbs is equal to the voltage in the batteries. If there are only two branches in a parallel circuit the current in the branches is equal to the total current. This is because the total current has to flow through two paths in this scenario, so half goes to one and the other half to the other.

This picture shows a complex circuit. In this circuit there is a series and parallel circuit. Just like the series the current stays the same until the current gets to the parallel part, the current splits and half goes through one branch and the other half of the current to the other. The voltage of the series light bulb is equal to both the voltages of the parallel circuit bulbs. The circuit light bulbs distribute half of the voltage to one and the other half of the voltage to the other.

Optics Reflection

I learned about optics. How there is concave and convex mirrors and lenses. I learned how to draw the mirror and lens diagram to figure out if the image can be formed or if it becomes virtual. Concave mirrors usually form real images, but sometimes they don't, and convex mirrors always form virtual images no matter what. With lenses it is exactly the same.
In this unit actually understanding what happens with mirrors and lenses was difficult, the equations and stuff were easy but actually understanding it was difficult for me. Example like knowing when the focal length was negative and just knowing when a number is negative.
My problem solving skills have gotten better because now i know now what i need to work on in the future. Like listen more attentively during class, and understand the labs that we do. My strengths in this unit were solving the equations and that was about it. My weaknesses were drawing the diagrams, and answering the questions about optics.

Flat Mirrors in a Camera

This picture displays the usage of flat mirrors in a traditional film camera that has a 50mm lens. I took of the lens of the camera off, and inside there was a series of three flat mirrors. One when you look into the camera and the mirror is at a slope, it is at a slope so the image that is shined through the lens is able to be seen where you look into the camera. The other two are used to see through the so you can take the picture. This picture is taken when the lens was not on the camera and the picture is of a reflection on the mirror from the other two mirrors. I took this picture opposite of what people usually take pictures. Instead of using the lens to take a picture, I used the viewer to take this picture. Flat mirrors create an image that is the same distance and height from the mirror,  the image is smaller because the mirrors inside the  camera are also smaller

Einstein Quote Reflection

"I never think of the future. It comes soon enough."

This quote by Albert Einstein says not to think of the future just live in the present. It could also mean that he did not plan any of his experiments or discoveries they jut kind of happened. When he says the future will come soon enough, that means the future will come eventually. He never thought of what was ahead of him he always thought of what was happening right now and what was right in front of him.
We can learn from this quote by living in the moment not thinking of the future and what will happen with our lives. We can also use it in the field of science by not think everything is going to happen a certain way, sometimes the certain way could be changed. Because something unexpected could happen, and if you were thinking in the future.

Conservations laws

Part A:
Energy is a conserved, substance-like quantity that is able to produce change. I learned the different way energy is stored and how it changes to become something else. We learned about kinetic, potential, and elastic potential energy and how to find them. We also figured out how to find work, which is a measure of the amount of change that a force produces. Also we learned about Power which is the rate which work is done. We learned how to make energy diagrams, with the energy of, kinetic, gravitational, elastic, and the energy to overcome friction. I have a difficult time using the work-energy theorem, just using and understanding it, i know its just the change of energy's but, just is confusing to me. To fix this problem i have to do more problems using this equations. Another thing i have found difficult was finding the elastic potential energy, same thing just need to do more problems involving it. My strength is in the bar graphs, finding kinetic and potential energy.

Part B:
Energy is in our everyday lives, when we drop a pencil or move something around. There is energy while people are walking and running. Every time someone turn a door handle or when someone picks up something. Energy is in our everyday lives in everything we do has some kind of energy to it.
