Ice Skating



Ice Skating is something I love doing even though I'm terrible at it. I can barely go straight and can NOT stop to save my life. My friends and I all went over break and it was so much fun. We did different things so in the end we picked how we wanted to apply it to physics.


When we got there, we realized that no one could skate in a perfect circle. 

Here is a video of Courtney attempting to do it: 


We then decided to ask this boy who looked like he knew what he was doing. I'm assuming he played hockey. 




Here  is what I did to find the centripetal acceleration: 

He circled around the bottom left circle which has a radius of 4.572m which I got from converting 15ft into m.

1 rev took 7 seconds which I found from watching the video and calculating how long it took to make a complete circle. 

V= 2π r / 7 

V =(  2π (4.572) ) / 7 

V = 4.104


a
c = v^2 / r 

ac = (4.104^2) / (4.572

ac = 3.68


Here are some videos from that day: 





Thanks to Julia Pimentel, Alyssa Pappas, Nathan Thimas, Yvonne Zeng, Courtney Marcos, Ryan Clary, and that random kid for being part of this!!

Physics of Black Holes...Or Lack Thereof

Isabella Jacavone To comprehend how the universe works, we must dwell into the most basic building blocks of existence; matter, energy, space, and time. NASA's  Physics of the Cosmos program involves cosmology, astrophysics, and fundamental physics intended to answer questions about the elusiveness of complex concepts such as black holes, neutron stars, dark energy, and gravitational waves. In this blog post, I'd like to elaborate on a subject that is very intriguing  to me; Black holes. And more specifically, what would happen if we got near one. A black hole is anything but a hole, but rather an immense amount of matter compacted into an extremely small area. A black hole is caused when, hypothetically, a star four times more massive than our sun collapses into a sphere no bigger than 600 square km. To put that in perspective, that's about the size of New York City. B lack holes were predicted by Einstein's theory of general relativity, which showed that when a...

The Physics of Spiderman

Over this past weekend after I finished working on my homework, I decided to relax and watch a few movies before going asleep. Among the movies I watched was Spider-Man 3 from 2007 and despite the movie flaws I was interested by the scenes that showed Spider Man shooting through the sky with the use of his webs that come out of his wrists. Due to this, I decided to make my blog post about the physics of Spider-Man's slingshot. After doing some research, I discovered just how much information there is on the physics of Spider-Man and how elements of Spider-Man can be used as examples for most topics learned in mechanics. For this investigation, I will not be using the horrible cliche and terrible CGI infested mess that Spider-Man 3 is but instead the all around superior Spider-Man movie of Spider-Man 2 to investigate the physics of Spider-Man's web propelled slingshot.  I want to talk about what happens in terms of physics when Spider-Man launches himself across a dista...

2017 Physics Nobel Prize - Capturing Gravitational Waves

 2017 Physics Nobel Prize - Capturing Gravitational Waves Gravitational Waves Captured by LIGO Who?  Rainer Weiss, Barry C. Barish, and Kip S. Thorne - LIGO/VIRGO Collarboration What?  Observation of gravitational waves for the first time using LIGO (Laser Interferometer Gravitational-Wave Observatory. Where?  Two locations in the US - Hanford and Livingston. (See figure 1) Figure 1: LIGO in the US When?  14 September 2015 HOW?  The scientists captured gravitational waves by using an interferometer. The LIGO interferometer is a more glamorous interferometer than the original Michelson interferometer. It works through using light waves to measure gravitational interference (i.e. waves). First, one needs to understand the parts of an interferometer. The LIGO interferometer (and most) is shaped as an L. It has two 4 km vacuum tunnel arms with a mirror at each end. At the center of the arms, there is a beam splitter. Th...
