How does a whistle work? In order for the typical whistle to work you need air streams. In order to get the high pitched noise that you hear coming out of a whistle you need the air steams to interact or cross paths. This is done through the round part of the whistle, as you blow into the whistle the air travels through the loop and up again (as seen in pic below) this allows the air to cross paths with the new air coming in. At this point where the air stream crosses itself again becomes a high
I'm really looking forward to this year in physics C. I really enjoyed AP physics last year and it sounds like this year we will be adding onto content that we previously learned which will be great. However, the class so far has seemed pretty terrifying, even though we have only been at it for about 6 days, the thousands of accounts to sign up for and the mountains of work hanging over our heads(which of course has potential to do damage hahaha) makes it look like we are in for a challenging ye
When you are walking in the snow have you ever noticed that when your foot lands in light, fluffy snow your footprint is actually bigger than it is and you can see the extra space with your foot still there? This happens because when you are bringing your foot down it traps a pocket of air between your foot and the ground. As a result of this once your foot hits the ground that air pocket is dispersed thus it causes for the snow around your foot to move even though you are not touching it. This
With this wonderful weather comes wonderful roads. From driving, it can be a very dangerous with the coefficient of friction much smaller making roads very slippery. Thinking about our previous unit with rotational and transnational motion it can relate a lot with a car in the snow. When starting up the tires often spin when very slick out causing for more rotational movement rather then the wanted transnational. And then as you get going you begin to build more transnational rather than rotatio
A human body has the ability to release a huge amount of strength through its muscles. The reason that a person is unable to unlock all of this strength at any given time is so that muscles do not get strained or torn in the process. This is a cool safety feature of the body so that people do not over exert themselves and end up crashing. In order to produce large amounts of strength it takes a lot of energy and using muscles to their max for a long period of time can be very harmful to the body
Thinking about what we have been learning in physics, on the topic of energy, it makes it more clear to see some of the physics that goes into taking a shot in hockey. I mean they go so fast but getting there was a little hard for me until this unite that we are in now. Looking at elastic potential energy you can clearly see that in the picture below. It's crazy to see how that potential energy is turned into kinetic energy in fractions of a second and the puck is sent flying at ridiculous spee
So last Friday our class of 22 had the pleasure of taking part in a Projectile Lab in which we would shoot our grade. In this lab we would be trying to hit a textbook after making various calculations. Another important aspect of this lab was the fact that if we hit this book the whole class would pass and if we missed the whole class would fail. As many of you know this lab didn't go so hot, crunched for time and lack of communication lead to a complete miss. Mr. Fullerton, being the wonderful
