  1. Car Tires

    That sounds terrifying!!
  2. Mr. Guercio's Brick

    I don't recall falling over his brick recently which is a good surprise!
  3. More Weather... Lightning!

    In my previous post, I discussed the physics behind hurricanes and their formation. After the crazy lightning storm we had last night, I think writing about lightning and how it connects to physics is a good topic for this next blog post. Lightning storms are an example of the electrostatic that occurs in nature. The result of the build up of the electrostatic charge in the clouds are those terrifying strikes. The lightning wants to take the path of least resistance where it branches out and grows. The negative particles in the clouds want to reach the ground which leaves the strikes coming down. Just like hurricanes, lightning is quite dangerous and everyone should avoid being outside during lightning storms. Everyone should also avoid standing outside with a large metal pole during one of these lightning storms unless you the desire to get struck by said lightning. Until next time, RK

    What a wonderful blog post!Physics is everywhere!
  5. Hurricanes

    Physics is everywhere in real life! Most people don't think about it, but weather is an aspect of physics. After all of the major hurricanes this year, I think looking at the physics behind the hurricane is a good idea. Hurricanes are formed when high air pressure intrudes in cold air pressure space which then rises and starts swirling and forming extremely high winds and destructive storms in a matter of days. The picture below shows why these storms are formed in the tropical regions and are able to create so much damage once it reaches land. The major physics aspect that I took from hurricanes is the Coriolis Force. This force follows Newton's Second Law but it has a rotating reference frame. When the force is applied to the Earth, it is often times called the Coriolis Effect. In most cases, the rotating object is the earth which helps account for some of the motion of objects on the earth. Looking from above, the object appears to move straight out, yet when looked at from a different angle, the object seems to have a curved path outwards. When hurricanes start to form, the air that is brought in is deflected perpendicular which also creates the spiral motion. This force also initiates the movement of the hurricane often towards land due to the rotation of the air. Once a hurricane reaches land, destruction will soon follow and remain. Until next time, RK
  6. A Quarter in Review

    I agree! We have all learned to work together and help each other to get through this class!
  7. A Haunted Blog Post

    I hope no one throws me a surprise party like that! That's a little too scary!!
  8. Roller Coasters

    Roller coasters are great examples the concept of conservation of energy. Using the knowledge that the initial energy should equal the final energy, we can use the equation Ui + KEi = Uf+ KEf . An example of a real life roller coaster that this equation works with is the Ride of Steel. The website gives the information that it is a 205 ft drop (62.5 m) but the total height of the ride is 208 ft (63.4). Even though the max speed of about 75 mph (33.5 m/s) is listed on the website, we want to confirm that information through the use of conservation of energy. We are looking for the max speed at the bottom of the first large hill. For this problem, we are going to say that the velocity at the top of the hill is about 0 m/s. mgh+(1/2)mv2=mgh+(1/2)mv2 ----mass cancels out---> gh+(1/2)v2=gh+(1/2)v2 -----plug in variables-----> (9.8 m/s2)(63.4 m)+(1/2)(0m/s)2=(9.8 m/s2)(.9 m)+(1/2)(v)2 -----solve for v-----> v=35 m/s Because some values were rounded to make the math easier, the velocity for the Ride of Steel does appear to be around 75 mph. Until next time, RK
  9. William Rowan Hamilton

    Before today, I would have never known who William Rowan Hamilton was. The only reason that I now know of him is because of a fantastic singing video about him. (It's a cool video, you should watch it!) Hamilton was an Irish mathematician in the 19th century who made many contributions to optics and classic mechanics. He was crazy smart. He spent his youth learning languages and then at 15 went on to discover an error in a physics theory along with contributing to other ideas. Hamilton discovered a number system that extends the complex number system as well. (ijk=-1) Overall, he was a pretty cool guy that now has a pretty cool song. RK

    That is the COOLEST thing I have ever seen!!!!!!
  11. A Box of Minions

    At the start, many of the yellow minions with cool goggles and a few strands of hair were captured by the evil Gru. Gru did not want them anymore so he decided to throw them all into a box to ship them off to an island in the middle of nowhere. Gru pushed the box at a constant speed along the ground that had friction. Once he got to the car, he realized that he would have to lift the box with a certain force. The work that Gru does is equal to the negative change in potential energy. He then flies the box of screaming minions to the island. Instead of just kicking them out of his vehicle, he uses a pulley system to reach a platform above him. He is standing with the box and himself on a platform and holding the rope. The power that Gru would have to use to sustain a constant velocity would equal the force times the velocity. From that point on the platform, Gru has a 1000 W electric motor that will raise the platform up a certain height. In 10 seconds, the box will raise that height as Gru runs away as fast as he can. However, Gru did not know that the minions had stolen the freeze ray and were waiting for the perfect time to use it... The minions stole the vehicle while Gru watched, frozen in place. Gru learned his lesson, never become an enemy of the minions. RK
  12. I Drop Everything

    Over the course of the past week, I have started to notice that I tend to drop everything. Anything from hair ties to binders to my phone. I am honestly surprised that most of the things that I have dropped have not broken. When we started learning about drag forces and air resistance, I began to notice how long the items take to fall. My math homework definitely seems to take longer to reach the floor compared to a small hair tie that seems to fly right to the ground. Even though we just took the test in class yesterday, I definitely need to focus a little bit more on actually learning the derivation for problems and making sure that I really know and understand it before I take the next test. I have been confused on the math of it since I read about it in the textbook but I hope that I can focus the next few days on getting it down pat. Until next time, RK
  13. Newton's Second Law Lab

    We definitely realized that there is always error!!
  14. Physics of the Candy Cane Sport

    When most people think about field hockey, they think about the stick that looks like a candy cane. The ball can only be played on the flat side of the stick which makes field hockey a difficult game to play. Newton's first law says that an object in motion will stay in motion until acted on by an outside force. When the ball is hit down the field, the reason it stops after some distance is due to the friction acting as an outside force which slows the ball and brings it to a stop. The surface that is played upon plays a role in the speed of the ball and in the end speed of the game. Grass fields are more difficult to play on with the grass because the ball does not cut through as quickly. Acceleration and changing directions also plays a huge role in the game because players have to quickly adjust speed and direction to dodge around the opposing team. Efficient dodging creates a space and cuts out the defender and makes their job a lot more difficult. That is all for now! Until next time, RK
  15. I am the queen of getting splits! My favorite split for me to get is the 3-7-9 because when the ball hits just right, the ball takes out the 3 pin then the 9 pin slides right into the 7 and it looks so cool!
