What is Physics?

  I got a couple emails.  SO if you have questions you can post them here. 

• The most important thing is that you have words @ least 25.  The more words the better.  
• Now organize them into groups.  
• It would probably be easier to do this on the computer because you can easily revise your groups
• Now look at your groups.  Whats the big picture?  What is physics based on your organization of terms?

First Days Keys to success.

It is important that you begin with the end in mind.
You will get exactly out of this course what ever you are willing to put in to it.

At times Physics in general can be difficult but, if you do things just to get them done what have you really accomplished.

The key to success is to try and learn and UNDERSTAND Physics when doing assignments and reading.
If you do this it will make things easier.
You will have questions when if you follow the above, I will be happy to answer those questions.

Snells Like Physics

1.
a. What is the speed of light in water, if water's index of refraction is 1.33?
b. If the wavelength of a ray of light in a vacuum is 1 X 10-6 m, what is its wavelength in water?

Note: something must remain constant. Is it lambda? Velocity? Or Frequency?
Now think of car on the expressway. What happens to them at the toll plaza. What two things must change? What doesn't change?

 2. Light traveling through air (n = 1.003) hits the surface of water (n = 1.33) with an incident angle of 30º. What is the refracted angle?



3. What is the critical angle of light traveling from water into air?

HP:Try these

• First identify the situation
• then write sum of F in X & Y

Program the quadratic on your calc!

goto programs

hit new

call it quad

input the following lines

using the programing menu

:Input A

:Input B

:Input C

:Prompt A,B,C

:Disp (-B+√(B^2-4AC))/(2A) 
:Disp (-B-√(B^2-4AC))/(2A)

now you can hit run or execute and it will ask you

a?

b?

c?

these are your a,b,c terms respectively.

 

Honors physics 1-12 questions and answers post um here.

Projectile problems HW.

If you are still having problems on the homework, you are expected to post them here. If not expect to have a quest on the material. You may post answers you are getting and ask for other students to validate, your numbers pictures or known values.

Solving using your TI.

While we the teachers would like you to be able to use your math skills expediantly, you have a technological marvel called a calculator, which when given the correct formula to describe a situation (your job), will compute a mathematical numerical value based on your physics. You are basically programing! Here is a a short video link that explains how to do this. Please if you have any question post them here on how to do this post them here. Extra credit: make a video (that can be posted online) of how to solve using a ti or your calculator one of the projectile problems from the hw.
