  1. During a sporting event, the players are the ones expected to perform physical activities. However, within the game and the stadium, there are many other types of physics. A few examples are waves. Waves range from the stadium fans, to the sounds of the players, to the light waves lighting up the stadium. One of the most common waves is performed by the fans, but must be done with a lot of concentration and coordination. A stadium wave has most, if not all of the crowd performing a transverse wave that usually has a very long period because of how long it takes to complete. A transverse wave i
  2. One of my most favorite people in history, is Nikola Tesla. Mainly for who he was as a person rather than what he did, but he did have huge contributions in the Physics world. Unfortunately, he is often overlooked by the average person, because of what the American, Thomas Edison, did with Tesla's ideas. Perhaps, Nikola Tesla's most well-known invention is the Tesla Coil. The Tesla Coil could produce high voltage, high frequency electricity. These coils create large electric fields that then can power other electrical devices around them such as light bulbs. Another invention of his that is wi
  3. One of the greatest natural wonders of the world are the Northern Lights, which unfortunately for us in Rochester, are usually only visible in the Arctic and Antarctic regions. After having been introduced to them in the magnetism unit, I became interested in finding out more about them. Their official name is Aurora Borealis and there is a ton of physics involved. The lights are created due to the interaction of the Sun's solar wind with the Earth's magnetosphere. From the solar wind comes charged particles, that are directed by the Earth's magnetic field to create different colors. These par
  4. Now that spring is almost upon us, spring sports will be starting up again soon. One spring sport that involves a lot of physics is track and field. From the throwers, to the hurdlers, to the runners, everyone has some kind of physics they need to perform and improve on. The sprinters focus on acceleration, velocity, and time. If we know that the runner has to sprint 100 meters, his time is 12 seconds and his final velocity was 8.3 m/s we can find his acceleration. We use the formula a=(Vf-Vi)/t and then substitute to make a=(8.3m/s - 0m/s)/(12s). The acceleration becomes 0.694 m/s^2. As for t
  5. Although an uncommon sport in America, rugby is a huge sport in the British Isles and southern countries like Australia, New Zealand, and South Africa. The great thing about rugby is how much power and work it takes to play. One of the main occurences in rugby that cause for so much work and power is a scrum. Scrums involve eight players from each team trying to work together in a pack to push the other pack backwards and get the ball from the middle. On average it is believed that a single scrum can generate a total force of 13,350 Newtons.However, if we were to look at a single team perfromi
  6. In most sports like football, basketball, and volleyball, being tall is usually very advantageous for the athletes. However, in weightlifting the complete opposite is true and people that are short have a much bigger advantage. That is because short people have a lot less work to do than tall people. Work is defined by the formula W=Force x Displacement. That's why it's so much easier for short people, they have a lot less distance when needing to lift something. To prove it I'm going to give an example of someone who is short and someone who is tall. Billy and Tom are lifting the same weight
  7. As I was trying to see where potential and kinetic energy are found, I realized that both show up within the liftoff and landing of planes. Starting from rest, the plane then gets onto a runway and starts to speed up rapidly. The speed of the plane and the huge mass of it lead it to have a lot of kinetic energy. As it sarts to lift off the ground and fly, the kinetic energy starts to turn into potential energy. Let's say that the plane which we'll measure at 1000 kg, gets up to a height of 1500 meters. Using the formula PEg=mgh, we can substitute the information we know to find its potential e
  8. Over the holiday break I traveled on a train to and from the city of Chicago. The rides were very long so I started to think as to how physics applies to trains. What I noticed is that the train was beng acted upon by Gravity going down towards the Earth while the Normal Force was pushing up with the exact same force in Newtons. Our initial and final velocity changed frequently from around 35 meters/second to 0 meters/second because of the constant train stops and start-ups again. Our trains couldn't go much faster than the 35 meers/second because the faster it goes, the harder it would've bee
  9. After discussing circular motion and how it works, I started checking where circular motion happnens in the world. One place that appeared interesting was on a helicopter's blades. When I started checking pictures, I noticed that at the centers of those spinning blades was a rotor that had a lot of mechanisms. That would make sense since the rotor would have to be able to handle a large amount of centripetal force. What is really unique about the circular motion in the blades is that they are strong enough to push the air around them and can also make a very heavy object fly in the air. The am
  10. First thing's first, if you have not watched the series of Quantum Leap, I highly recommend it and it's even available on Netflix for all you Netflix lovers. After watching the series I realized I was never actually educated in what Quantum Phisics is. The show makes several references to string theory, and the main plot of the story, which is time travel, but I never had a good understanding of the important details. That being said, now that I am taking physics I am hoping that we might learn a little bit about what Quantum Physics deals with and how it works. I have done very little researc
  11. Now that we have started learning about forces in class, I have been able to relate that to an everyday activity of mine, which is working out on a punching bag. I have a stand-up punching bag which is affected by both the force of gravity as well as the normal force of the floor. Once I add an applied force of any type of strike, it will move in that direction at the same velocity of my strike. However, I realize that no matter how hard I hit the bag it will always offer an equal reaction to my strike.(Newton's 3rd Law is applied here) For example, if I hit the bag with a force of 100 Newtons
  12. Throughout the fall and winter seasons, I watch a lot of football games. I think physics is applied to football in many ways like, when the football is thrown, acceleration of players from rest to when the play is going on, and also in kicks which have similar characteristics to throws. Kicks and throws both have the football moving in a parabolic path to its target with an initial velocity and with gravity forcing the ball back down to the ground. The players themselves constantly go from rest at the beginning of a play, accelerating, and then usually get hit by a player of the opposing team.
  13. Breaking News This just in from Irondequoit High school, we have found the acceleration due to gravity. Physicists Peter Martin and Mike Vrooman discovered this finding with a state-of-the-art lab. Materials consisted of a gator skin ball, a stopwatch, and a meter stick. They conducted the experiment first by measuring a set distance to drop the ball from. Then one of the physicists would drop the ball from that set height and start the stopwatch at the same time. They would stop the stopwatch when the ball hit the ground. They replicated the test several times to filter out the error. Then u
  14. Over the last few weeks I have learned a lot about physics. I learned that speed and distance are scalars and velocity and displacement are vectors. A scalar has only magnitude, while a vector has both magnitude and direction. Speed is the rate at which distance is traveled, whereas velocity is the rate at which displacement changes. Distance is a change in position, while displacement is a straight line vector from start point to end point. While taking physics I have struggled mainly with the writing portion of the lab. This was my first lab all year so I'm sure I'll improve, but I didn't qu
  15. For this project we measured the speed of cars on cooper road. We wanted to see whether cars were following the speed limit. We measured out 10 meters2 people used stopwatches measuring the time it took for the front of the car to go 10 meters. Also when people were timing the car, another was recording the details of the license plate and color. Took the average of the 2 measurements Converted our data into meters per second This is the data we found Car Distance (m) Time (s) Speed (m/s) B7E 2186 10 0.9
  16. An activity I perform where physics is applied is martial arts. I think physics applies to martial arts because all the movements are meant to be efficient and quick based on how your body can perform those moves. the goal is to always find the most effective way of completing movements which requires knowledge of some physics. (Distance from target, speed, power, etc.) I am taking physics this year because i thought it would be the most interesting science class that I could take in high school. I also am not a big fan of other science classes like biology or chemistry, so physics was the bes
  17. Hello Isaac, I too enjoy watching all kinds of sports. Like you I also thought physics seemed like an interesting science class.
  18. Trevor, I was fascinated by your life. Yours is truly interesting. What specific medical career are you pursuing and how would physics help with that?
  19. My name is Mike Vrooman. I am a Junior at Irondequoit, but have only been a resident of Irondequoit for a little under two years, as I came from Rush-Henrietta. I am half spanish because my mom is from Spain and I even lived in Spain for several years. In the future I would like to be either a sports writer or a police officer because i enjoy talking about all things sports and i have always been interested in trying to help the community to the best of my abilities. That's my life at this point in time. I am taking physics this year because I always felt it would be the most interesting o
