    Light's Out

    Friday April 10th might as well have been Friday the 13th!!! Due to the very strong wind, the traffic lights on Cooper and Titus were knocked out. Unfortunately, several businesses around that area also felt the wrath of Mother Nature, suffering from power outages themselves. I work at Cam's Pizzeria as I have mentioned in my previous blog posts, and my place of work suffered from the power outage but heres the catch... only in half of our store. What does this have to do with physics you say? Well the part of our store that of course had the oven on it did not receive power. The fryers worked and of course the sub bench but nothing involving pizza. A few lights worked and a few switches didn't. Why is that?? I think it has to do with the electrical circuits. The lights that were still on probably operated by parallel circuits so they had more than one path to travel as a back up. The ones that were out immediately, like the oven, were probably powered by series circuits, and only had one path to go through, shutting the light source off completely. Eventually, (8 hours later), the power was back on. After dealing with rude customers who were not understand and turning away about 5 French foreign exchange students, everything was back to normal and we could serve pizza again. (:
  5. In Orchestra, we are currently rehearsing a piece entitled "Danza" composed by some hotshot 21st century guy who has no respect for the left hand of a cellist. After the first 53 measures, my entire section plays a series of D's. By a series a mean 500+ until the end of the piece. Its both irritating and painful after a while. As my pinky crinkles up into nothing at the end of the period, I think of physics. I'm exerting x amount of force onto the neck of my cello, onto the spring to play the note. My cello is exerting the same force back onto my poor pinky! Newton tells us that forces come in pairs, equal and opposite. I honestly wish Ms. Murrell would have picked a piece that wouldn't leave me with arthritis in my pinky, but her decision is final :/. I cannot wait until March, where we play this piece for the last time and my pinky can start its recovery.
  6. So basically we put out Christmas tree up 4 days before Christmas. That being said, we were not about to take it down 5 days later! Or even after the New Year apparently... ANYWAY, our Christmas tree was finally taken down last weekend. But upon taking it down I realized that the unit we were doing in physics really related to our tree, or the lights at least! Christmas lights use both power and energy, which are measured in watts. When the lights are off but plugged in they have a certain amount of potential energy and a certain amount of kinetic energy. The total mechanical energy stays the same throughout the process though. Any energy not accounted for or "lost" is converted into heat! Because of course we know that energy cannot be created or destroyed. The whole process of the lights obviously involves an electrical part of physics that we obviously haven't reached yet in the curriculum but I cant wait until we get there!

    Today while stocking the coke cooler at work, I also had to simultaneously arrange the left over bottles into neat rows from their soft, plastic containers. After I had them all arranged nicely, and stacked on top of each other, a few of the containers that I didn't have room for fell over. BOOM! It was so embarrassing, customers looked to the back and my boss gave me a look that could kill. Shaken up soda flew everywhere. I realize I only have physics to blame for this! I bet I could figure out the time it took for all of the bottles to hit the floor if I used Kinematics. The bottles fell because the force of gravity pulled them down. They had an acceleration of approximately 9.81 m/s^2 downward, with an initial velocity of 0, and a distance of about 1 meter. If I used d=vi(t)+1/2(a)(t)^2 and solved for t I could definitely find the time it took for all of the bottles to fall and for everyones eyes to focus on me :/ thanks a lot gravity!

    Ice, Ice, Baby....

    About two weeks ago I went ice skating with some friends of mine. It was so much fun and I didn't even fall! But both myself and my friends' amateur moves were put to shame when a few couples started showing us how its really done! They twirled, they spun, they jumped and twirled some more. There's a lot of physics in fancy ice skating- er, figure skating. First of all, we see Newton's first law: an object at motion stays in motion until acted upon by a force. The ice skaters glide across the ice because its Force of Friction isn't big enough to actually stop them; they put a force on themselves to stop themselves by dragging their skate on the ice. Unless they drag their foot, they'd just keep going. We also see Newton's Third Law, for every action there is an equal and opposite reaction. For the couple that did the jump turns, as they pushed off of the ice with their skate the put a force on the ice, and the ice put the same force back on the skater which caused them to go up. Though I can't do fancy tricks that involve tons of physics, I still had loads of fun.

    theres so much physics everywhere! I cant wait to read your blog posts about your new job (hopefully!) and then we'll be able to relate to eachother!
  10. A couple of weeks ago, when we received a TON of snow and it was -15 degrees (but still received no snow/cold day), I sadly had to drive to school. Before driving to school I had to pick up my friend Natalie. It usually takes me about 20 minutes to get from my house to school, but this day it ended up taking me 35!! On the way, everyone drove like old ladies (naturally) and even going 20 mph I found myself sliding and being sucked into the slush and ice; it was terrifying!!! I read somewhere that to come to a stop, in bad snowy weather, it was important to pump the brakes and not slam on them. There's actually lots of physics just in a car. Pumping is better than slamming because of friction. When you slam on the brakes, there's still Kinetic Energy in your tires, causing you to keep sliding and moving, which is all very scary (DONT do that)! By pumping the brakes, as I did, Natalie and I got to school safe and sound.

    Physics of GTA

    NEATO! way to apply physics to one of your favorite hobbies
  12. wow really sounds like you know your stuff, Jess!

    physics in disney

    that's so cool! that ride sounds so fun AND its all about physics! >o<
  15. chewy is so cute! you should post a picture of him doing this next time!
  16. Recently, I've been trying to get into better shape so I've been going to the gym. As part of my cardio routine, I grudgingly run on the treadmill. After about 15 minutes I find that my knees are in unbelievable pain (gosh, I despise the treadmill)! I have realized the reason for my knee pain! It has to do with Newton's Third Law! As I'm running on the treadmill, my feet are putting a force on the treadmill, and the treadmill puts a force back on my body. Though I have a greater acceleration than the mostly still machine, the machine has much more mass than I, and though the same force is pushed back, I still feel more pain in my joints. After icing my knees and calves, and shedding a few tears, I've come to the conclusion that I will take some time off of the treadmill and work on other cardio machines to avoid possible amputation of my legs!!! That was a bit dramatic but anyone who has run on a treadmill for a while knows the pain that I am referring to. I blame physics for my aches and pains

    Phony Physics

    Wow I never really realize all the physics around us until its pointed out to me! That's super cool!!!!!

    I work at Cam's Pizzeria on Titus. It's a really fun place to work and I love the people I work with! At work, I've noticed a lot of physics. For example, the pizza chef constantly complains that their wrist hurts throughout the night. After an eye roll, I finally realize why their wrist might be sore. It has to do with Newton's third law. The pizza chef is pressing on the dough with a force, and the dough presses back on the wrist with an equal and opposite force. After about 10 pizza's, the chef is holding their wrist in agony! It's hilarious! I realize theres physics all around me, in every aspect of my life.
  19. We had a lot of trouble making our catapult too! It definitely was a challenge, glad you guys had fun in the end!

    Lacrosse Problems

    Oh my gosh I hope youre okay! physics really is all around us!!
  21. Last Thursday my class launched our catapults on a football field. My partner and I, were a little bit frustrated with the project, having little experience with power tools and building mechanically sound structures. The day of the launch we were both nervous and excited; our catapult was among one of the smallest on the field. We attempted to get our softball to launch at a 45 degree angle, seeing as that is the best angle for the greatest distance to launch. Unfortunately, our catapult went about 1 m every time we launched it. It was still fun despite the rain! There were huge catapults that went a small distance as well. We felt proud of our little catapult Here's a picture of it:

  23. Introduction: We had to find the speed of 10 cars on Cooper Rd. The speed limit is 35 mph but a lot of cars exceed that. We had to try and find out the speed of the cars based on the distance they traveled, and the time it took them to travel that distance. Procedure: Set up a tape measure to make sure it was 20 m in length Next, set up a timer to time each car from bumper to bumper, how long it took to travel the 20 m. Put two people at each marker and get rid of the tape measure. Record data. Repeat steps 2-3 for each car. Conclusion: Something we could have done to improve our data is having two people timing the cars instead of just one. It would make our data more accurate. We could re-do our experiment on a different day at a different time of day to see if people drive different speeds then. No there is not a speeding problem on the section we measured on Cooper Rd. People are more cautious directly in front of the school because it’s a school zone and the speed limit is slower. Also there were a bunch of kids standing out by the road which might cause drivers to drive slower than usual. In conclusion, speeding on Cooper Rd is not a problem because people are driving under the speed limit which decreases risk of accidents.
  24. Hi my name's Kalea (kuh-lay-uh) and I am a senior here at IHS. In my spare time I love to run track and play field hockey. When i'm not in school i'm working, and when i'm not working i'm sleeping. When I'm not sleeping I'm usually buying something online or in person that I really don't need! I am looking forward to my senior year! I took physics because I generally enjoy sciences, and I didn't want to take environmental or AP Bio but I wanted to take a science. Which left this and AP Chem so with the toss of a coin this won! I hope to learn stuff about space and how gravity and other forces affect the human body. I'm hoping to come out the Regents feelings great! video of a skill needed to be successful on the field:
  25. that's so exciting that youre captain!!! I think seeing how physics plays into the body is interesting also!!!!
