  1. Waves they're everywhere. They're apart of our daily lives. We experience waves 24/7 whether its from sound waves, light waves, etc.! In this blog post I'm going to be discussing several examples of waves in our daily life. Light waves- The sun is the main source of light waves on earth and require no medium to get to us. Sound Waves- These waves require a medium to get to us. For example if you put a bell in a vacuum sealed, air tight case and hit it then you wouldn't be able to hear the bell but you could still see it. This is because light waves don't need a medium but sound waves do. This sums up a short summary on waves thanks for reading.
  2. Sound waves are everywhere. They're heard in the car, on a plane, and even in our back yard. This is especially relevant when it comes to my dog, a 175 lb(and still growing) Irish Wolfhound. The dog's name is Maximus, Max for short. Max is a loud and obnoxious dog at times. He is constantly barking at everyone and everything. His bark is loud and deep, so he usually wakes the cat, me, and my family up at night. Whether I like it or not he likes to transmit a sound wave that is loud. His sound wave travels fast enough to make the cat jump about 2 feet off where she was laying. It is actually amazing at how high the cat can jumped when scared by my dogs bark!! Well that's all for now thanks for reading.

    F=MA?

    Recently over our Spring break, I encountered a shocking event of physics. I was having a poker night with my friends. Most of us were just sitting down relaxing and out of no where my friend throws his hand on the table, gets up and goes in the other room and we hear a thump... I immediately got out of my seat and made my way into the kitchen to discover that my good friend loved to use physics in his everyday life! He decided because he was losing and had a bad hand that he would take his mass of his fist and exert an acceleration on it to create a force into my wall! This not only hurt His hand but the wall too. Every force has an equal and opposite reaction. He gave a nasty bruise to my wall(aka a huge crack) and then in return it gave him some nasty bruises back. He ended up fixing the way later on. All and all I'm glad my friend knows his physics!!!

    Resistance

    Resistance is the ability to not be affected by something. In this case we are talking about circuits, and we are resisting the current provided by the battery. Resistance in a circuit can be anything. This could include a lamp, an appliance, or just about anything that needs power. Resistance is even in the ammeter, although it is incredibly small, and in the voltmeter, which has a huge resistance to not affect the flow of current. Resistance is vital to a circuit because if there is no resistance the current will flow freely and if fast enough it will heat up the wires. This could eventually cause a fire if not dealt with. This is why we have circuit breakers in houses, to slow the flow of current so it doesn't overheat the wires and cause a huge fire in your house in between the walls where your wires run. The area in between your walls is highly flammable with dry wall and insulation in between it. This is why Resistance is so crucial to a circuit (and its survival).
  5. Every one has a cellphone. Almost everyone has their cellphone on them at this exact moment. This means everyone has an electric circuit on them. Your cellphone when not in use has about 50-60 volts of power flowing through it. These electrical circuits are everywhere. Your house has countless amounts of circuits in it as well. From your outlets to your hair dryers to video games we use circuits constantly. This would include series, parallel, and even a combination of the two. It's astonishing to think how many times we use circuits of something that is operated by circuits. How many times a day do you use circuits?
  6. I recently had a realization in physics, that it actually applies to outside in the real world in a lot more ways then I thought! I was recently doing test work for my first year physics class. I was having some trouble with distance vs. time graphs, velocity vs. time graphs, and and acceleration vs. time graphs. I have a much higher understanding for math than physics in my life right now so any relation I can make from physics to math is incredibly helpful. I have recently connected the use of derivatives and integrals in physics. I realized that going from a distance to velocity to acceleration graph is the same as taking the derivative. The same idea going backwards except taking the integral of the function. Being in an introductory physics course the students don't get explained this yet because it's only basic level math with no complicated functions. So I had to figure this out on my own. I am quite proud of myself for coming to this new understanding because now I will not get questions like this wrong anymore in the future and I have a taste for higher level physics in the future( which I am excited to get to now!).
  7. Physics class is something of astonishment. It's a class where as you're being taught the material you can see the effects working directly in front of you. Don't believe me, well look for yourself! The physics room is full of physics itself. Take a student for example. A student is sitting in a chair, what are the forces? Well there's gravity acting upon him and everyone else pushing him and us towards the earth. Luckily that's not the only force or we'd be squished like a bug. There's a normal force of the ground(and the chair) pushing right back equal to the force pushing down. Even as you stand there now reading this post there are forces acting on you! You can't escape the physics no matter where you go, even in space there will still be some physics applied!
  8. I was playing tennis the other day when I smashed a shot into my partners chest. After almost falling over from laughing so hard I stopped and thought about the physics of what just happened. I realized that if I recreated the events timed it, measured the distance, I could determine how long the ball was in the air using my kinematic equations! I'm sure the data will be a little off but the ball followed a parabolic arc and immediately stopped when coming in contact with my friends face...(he was ok about ten minutes later~nothing a good pat on the back can't resolve). I even began to think of Newton's third law in this case. Every force has an equal and opposite force pushing back. As that ball came to hit his face, his face(mostly his nose) pushed back with the same amount of force. I truly have to say that I'm astounded that I am able to relate my physics to hurting my friends and get a good grade for it...Thx Mr. Fullerton keep up the good work!

    Catapult Project?

    Catapults are one of the deadliest war machines ever created...and we got to create one in our local high school physics class! This year(and maybe the last) Irondequoit High School physics students formed up in groups of three to make catapults to launch softballs. My team and I worked diligently to create our own little war machine. We spent $98.68 and at least 10 hours of hard work on our machine. Regardless to say after building this beast, called the "Eviscerator", we tested it and got 30 feet the first time. After some set backs and some modifications on launch day we reached an astonishing 10 yards in the final run!! Now I know what you're thinking, that's pathetic especially for the size we built it as, but I had a blast. My friends and I worked each night to slowly constructing this beast. We had a blast, just the idea or working together, telling our jokes, and building a catapult still makes me smile. I loved every minute of it, even transported the huge thing (our truck steering broke half way home so it took three people to turn he steering wheel!!!). That was the best part and I'll never forget it. With this project alone I've realized the importance of physics and the fun that can come with it.
  10. I am currently a student at Irondequoit High School taking an introductory physics course. I have been working hard in the class for a quarter of the school year and I'm amazed at what I've seen. Physics to me is so astonishing. It is amazing that some dinky little math calculations can be translated to the real world to account for how things work(Not saying physics is all easy math, because its not). I love the ideas presented in class and everything about it. I love learning how to calculate things so I can make them happen in real life. Now this may sound a little dorky but this is crazy to me, maybe that's why I want to be an engineer. I can't even began to describe the new ways I have looked at things now. Only a quarter in and I'm already on the edge of my seat waiting to learn more. I can't thank my teacher, Mr. Fullerton, enough. He's left a phenomenal legacy in this school and has greatly impacted my decision to include physics into my future career. Thanks.
  11. Another interesting use of physics. Again I am amazed at the amount of things this subject can relate to, whether it be swimming in finals, building a rocket ship, or just plain out walking. It's very interesting to find that people today, even when skiing, can find physics being around them. Keep up the good work.
  12. very interesting thought. I never saw thought of moving in water that way. I guess the dame can be said when walking, when you walk you push back against the ground. Oh and good luck on sectionals Friday!

    Catastrophic Catapult

    The design seems very similar to ours. Maybe you could of used something like grease to ease the friction on the pin and the wood. If you added some grease then It would definitely slide easier but might not solve the problem.

    Catapult Plans

    Recently my team and I, Dennis, Alex, and Joey(me), are going to be working on the catapult this weekend. We already have the picture drawn and have a great plan in place. We are trying to use 80 lb weights to launch the projectile at least 100 yards. That's the goal anyways. We will be back to post final results and maybe our early plans.
  15. DJ Walker Mr. Fullerton Joey Mantione 10/3/2014 Physics at Irondequoit High School? Breaking new at Irondequoit High school. Young Physicists Joey Mantione and DJ Walker have found a novel way to calculate the acceleration due to gravity. They worked countless minutes to establish and create experiment procedure that worked almost as hard as they did. The procedure, although challenging, was done at a timely manner. First one of the students took a dodgeball and stood atop a table approximately 2.53 meters above the ground. Another student, with a stopwatch in hand, timed the amount of time from the release of the ball to the ground. This trial was repeated three times and then averaged to be about .76 seconds until it hit the ground. With simple math the young geniuses concluded that the acceleration due to gravity in their experiment was 8.76m/s/s. After their experiment the boys went to work to determine the accepted value of acceleration due to gravity. Through countless work and research they used their most reliable resource, their teacher. Through their teacher’s infinite knowledge the teacher concluded that the accepted value is 9.81m/s/s. Realizing that there was some errors to the experiment, including the boys timing the ball correctly and even air resistance, the young physicists calculated their percent error which was 10.7%. Through their incredible work the boys have contributed to the physics community again. This is the physics news now signing off. Goodnight America.
