  1. So everytime I need to make blog posts I always try to connect what we have been learning in physics to my favorite sport: softball. Now you might think that there are no waves in softball but I am creative and I believe I have found some sort of wave while playing softball. When people throw a softball really high it creates a giant lob that looks like a parabola. And this lob could also look like a half a wave. And if you measured from the ground to where the highest part of the ball reached, you would get the amplitude. But of course, the so called wave would never be finished you would onl
  2. When I was little we would always play this game with the jump rope we would call "snake". Two people would hold either end and kneel at the ground and wiggle the rope parallel to the ground causing waves to be going back and forth on the ground. And the object of the game is to jump over the jump rope without the "snake" getting you. First you would start off small, with little amplitudes. An amplitude is measured from the baseline to the top or bottom of the wave. And as the game progresses the snake would create bigger and higher amplitudes to make if more difficult to jump over the snake.
  3. A very important equation that we have learned is V=fh. The V is the velocity. The f is the frequency. And the h (which looks like a fancy backward h) is te wave length this is called lamda. The velocity of air in STP is 331m/s. How we applied this equation is questions would be asking you to find something in the equation. So for example if you were asked to find lamda given the velocity, you would plug in what you have and solve. Like if the wave was traveling at a speed of 10m/s and the frequency is 5 hz. You would divide 10\5 to get the wavelength of 2 meters.
  4. I am going to myrtle beach for spring vacation!! So I figured I would talk about the waves I will see on the beach. The waves at the beach are transverse because they move up and down. As the water moves to shore the waves move up and down. People can cause a disturbance in the water distrupting the waves path. The best waves to surf are ones with really high amplitudes. When the ocean is angry the amplitudes are even higher! I can't wait to go observe the waves on my vacation.
  5. We have been learning about waves. A disturbance is called a pulse. To measure amplitude you measure from baseline to crest or from baseline to trough. Transverse waves can only move up and down. Longitudinal waves move parallel to the wave. Sound waves require a medium. Sound waves are longitudinal. Mechanical waves also require a medium. That's it folks. Peace.
  6. As we all know the Winter Olympics are rapidly approaching, so I would like to do my entry about the physics of curling. Awhile back we learned about friction is the resistance that one surface or object encounters when moving over another. And as I understand the object of curling is to get your stone to the center, and knocking other people stones out of the way. There are also sweepers that go in front of the stone to smooth the ice to make the stone go faster. This involves friction. The more they brush the less friction they are creating. They use friction to place the stone where they wa
  7. Last unit we learned about work, energy and power. And I noticed something when I went to the gym. I was on a cardio machine and i saw that it was telling me how many watts I was producing. I remembered in class that we learned about watts. They are the units of power, joules over time. So I guess that while I was working out, it measured how much power I had. And when I started to to faster the watts went up. I was producing more energy in the same about of time which will increase the watts as a result. Who knew that going to the gym would involve physics.
  8. Right now we are in the unit of work and power. Work is the process of moving an object by applying a force. And for a force to have done work on an object it must have caused a displacement. And also the force and displacement must be in the same direction. The formula is W=Fd. The W standing for worl. The F as the force. And the d standing for the displacement. And the units for work is joules. Power is the rate at which work is done. The same amount of work can be done with different supplied power if the time is different. The formula for power is, P=W/t. And the units for power are watts
  9. Now that the winter has arrived, ski season begins. And physics is involed everywhere in physics. Especially with our current unit about power and work. Work is the process of moving an object by applying a force. Power is the rate at which work is done. When skiing, the ski lift does work on you. Everytime you go up the ski lift, it is lifting you and your mass up the mountain. Also when people get hurt, the ski patrol does work on you. Because when you are in the little sled that carries you down the mountain, the ski partol has to pull you down the mountain, thus doing work on you. As you c
  10. Last unit we learned about circular motion. And circular motion can be applied in many places while playing softball. One instance in particular is when you are pitching. I am a pitcher and circular motion is involved alot considering your arm is traveling around in a circle. If you were allowed to have you arm travel around more than once you would be able to find your arms centripetal acceleration by using this equation: A=v^2/r. You could also find the frequency aka the number of revolutions completed in one second. And also the period of your arm which is the time it takes to complete one
  11. The unit that we are going right not is impluse and momemtum. I have learned many new things about these topics. For example, the definition of momentum is how hard it is to stop a moving object. And the definition of impulse is the change in momentum. We also learned many equations for this unit. Like, p=mv which will help you find momentum. Also J=Fnett=change in momentum=mdeltav. All these equations can help find impulse. And it is easy because everything equals everything. Lastly i learned that momentum tables can really help you out while trying to solve problems. If you use a momentum ta
  12. You may not know, but there can be a lot of physics involved in doing calculus. For instance after doing homework for several hours at night and you discover that you have been doing it all wrong, you might feel the need to crumple up you wrong work and throw it across the room. Doing this can I involve physics. When you launch the paper it would be at a certain degree. Knowing the ideal angle is 45 degrees you would get as close as you can to that angle to launch you homework as far as you can. You would also launch the paper at a specific speed. You wouldn't know the actual speed when throwi
  13. That's cool, I didn't know you played soccer
  14. So I've already done softball in physics before, but now that we have learned new material I thought I could show more physics that applies to softball. Projectile motion is everywhere in softball. When you throw a ball the ball will almost always make a parabola. Which is the shape of the projectiles we have been looking at in class. Also you can use projectiles when trying to see which ball will go the farthest at the same velocity. If the ball goes higher it won't go as far as a ball that's thrown lower. So this is all I have so far for physics in softball. Hopefully we will learn more and
  15. New Kinematics and Gravity Lab: In this new lab we will perform the experiment outside. We could either use a rescue window or go out to the turf and drop the ball from a higher place. In this example you and your group will go out to the bleachers. You will need a stop watch, a ball and a tape measure. To begin the lab you need to calculate the distance from the bleachers to the ground. Using the stop watch, time how long it takes the ball to travel to the ground. You will need to repeat this multiple times to get an accurate representation. After using the information you collected, determi

    I wish I could play volleyball!
  17. Wow Hannah you have learned a lot!!
  18. In softball, physics is applied throughout the sport. For example, when you run from home to first base, you start at a velocity of 0m/s and it increases as you run. Also when you round the bases when getting a double or triple, your velocity decreases as you approach the base and then it increaes and slows down again as you run around the bases. Also when you are hitting the the pitcher throws the ball and when you hit it the velocity with be 0m/a until the ball bounces and it's velocity increases again. As you can tell physics can be applied everywhere when playing softball.
  19. The speed limit on Cooper Road in front of Irondequoit High School is 15.6 m/s. However, drivers do not always follow the precise speed limit. We collected specific data to discover the average speed of automobiles driving down Cooper Road. To do this, we measured 50 meters, and marked the 25 meter and 50 meter spots for two individuals to stand at with stopwatches. In addition, one individual stood at the beginning of the 50 meters and indicated when a car drove past them. This would signal to both individuals with stopwatches to start the timer. When the car drove past the individual 25 mete
  20. Being an Eagle Scout will help you problem solve and be a great builder for the labs in class this year
  21. Hi Reed, I cant wait to be your physics lab partner
  22. Hi, I am Stephanie and I am a senior. I am excited to start my senior year in high school. I play tennis for the school. I have been playing for three years now on the team. I also play softball for the school. I have been on the school team for my fourth year now. I play pitcher and 1st base. When I am not playing for the school I play in a travel league named Webster Xtreme. I have been playing on this team for my third year. I cant wait to play my last year of tennis and softball for the school. The reason why I am taking physics this year is because when I plan on applying to colleges,
