I've finally trained my little girl to yell Doppler Effect when an ambulance goes by!

Let's take a look and see if we can't prove it one way or the other with physics!

Very cool... I spent last Saturday in Syracuse talking to two physics teachers who spent last summer at CERN... great to hear such interesting and groundbreaking research! I can hardly imagine the ramifications if this is verified!

Excellent job extending theoretical concepts to real-world applications. So, if both mass AND velocity are important in analyzing a collision, what physics quantity do you think we should use when we look collisions in football?

Nice job everyone. Just for future assistance, if you want to attach a file, use the "insert picture" button, and the server will put a local copy of your graphic on the server so it can be seen by everyone. [ATTACH=CONFIG]178[/ATTACH]

Close, it was called Tatooine. :-) Trying to out-nerd a physics teacher... that's just silly. Great post, and I like how you're thinking about the physics of how such a situation could exist. Do you think it would be difficult to model the gravitational field in space for two suns, if the gravitational field strength is a vector? This sounds like a great opportunity for us to try out our new simulation software, Interactive Physics!

AP-C Physics can be frustrating and challenging, and at times may seem overwhelming. It's also one of those courses that will leave you feeling out-of-sorts on various occasions. And I'd like to tell you that feeling will go away, but in all honesty, as you are finally pushed to these new challenges that are uncomfortable, it really doesn't go away. In fact, the challenges you're going to continue to face make this feeling grow and grow. BUT, I can tell you, that the more you stick with it, the more you get used to the feeling. You'll realize it's OK to be frustrated and confused, especially as, time after time, you struggle with the material, occasionally get knocked on your butt, but get back up again, and build the confidence to realize you're good enough that you can tackle these problems and challenges that seem so insurmountable when you encounter them. I could give you lots of reasons to stick with physics that have to do with college credits, career paths, where you'll use it later in life, but they're all minor details compared to the most important one. You should stick with it precisely because you're not sure you can handle it. As opposed to letting go and not knowing, dive in and find out... prove it to yourself, for yourself. It'll be hard at times, and it'll push you past the boundaries of what you ever thought you could do -- but if you stick with it, you'll come out better for it on the other side. And you don't have to do it alone. We're ALL here to help you succeed, even when that help sometimes feels like letting you sputter and flounder in the water. Have faith you're not going to sink. I do. :wave) (PS -- best advice I can give you in physics C -- quit worrying and stressing. If you do your best each and every day, you've got nothing to stress over, no one can ask any more than that of you, I'll be proud, and most importantly, you should be proud!) Take a look at the student blogs from last year, such as this one... you'll find many feeling the same way, and as you read how they progressed throughout the year, note how much more confident they get. It's a journey!

Well done, and great job sticking with a concept that was "fuzzy" upon first introduction... that'll happen a lot in AP-C, but familiarity will make it easier and easier!

Physics of running and drafting -- very cool!

I have a scanner we can use!

I do! I do! (Hint -- check your online course calendar).

Interesting ride to understanding the Doppler Effect... and you found yet ANOTHER use for AP economics! :einstein)

Welcome to APlusPhysics, gburkhart4210! Looking forward to reading your blog...

Welcome, MrPhysics, and best wishes on an amazing 2011-2012 school year! :wave)

Have no fear BrightBulb -- over the next couple days we're going to lose everybody for a bit, but we'll also having you thinking this stuff is easy by the end of the week!

Somehow I think you'll end up with more topics for weekly blog posts than you imagine. If you want a great example, check out Rhett Allain's dot.Physics blog!

Don't blink!

It is going to be tough, but it's going to be fun too! If it were easy, they'd call it chemistry! http://www.cafepress.com/aplusphysics.527644408

Have no fear BrightestBulb, nobody gets this course 100% the first time through it. Every time I teach it I learn something more, and I don't think that'll ever change. If you make it through any physics class, and think you understand everything you learned, you probably weren't paying attention. It takes time for things to start making sense, sometimes a few hours, sometimes days, sometimes years. That's OK. Do your best, MAKE it fun, and you'll be a success!

Have you ever seen the show Sports Science? It's a fun one to watch, not only from the physics and application side, but occasionally they "mangle" the physics a bit in their explanations -- would make a great blog topic if you catch an episode (I have a couple examples of snippets from the show we'll see in class this year too).

Thrilled to have you aboard, goNavy51 beat Army!:labmate)

How intriguing! :einstein)

I was amused... thrilled to have you aboard Entropy Fiend. The good news with your note-taking strategy is that if you ever do want to go back and reference our class notes, you can find 'em all online at http://aplusphysics.com/wordpress/regents/

I think you're going to enjoy physics breezy, and if you give your full effort, I have no doubt you'll be successful!
