Free Body Diagrams

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.

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.

HP: Forces and Newtons Laws

Ok This is where we are going now.  You should read the chapter on force chapter 6.  We are on a tight schedule.  Please if you have questions ask stop by ect.  better yet schedule a time.   Students from other classes come in for help why not you. 

• Forces-Newtons Laws
• Torque and Rotation (see-saw Physics)
• Energy  (conservation)

Honors Physics Projectiles HW Check Your Understanding

Uhh.  Got Questions?  Need answers?  Help?  Rely on the kindness of anonymous strangers.  Post your questions comments here.  The first person to post a pertinant response will recieve a prize!  No not really.  Try starting with the rules of projectiles...

HP: VECTORS OBJECTIVES

• Determine graphically the sum of the magnitudes of two or more vectors.

• Solve problems of relative velocity.

• Establish a coordinate system in problems
  involving vector quantities.

• Use the process of resolution of vectors to
  find the components of vectors.

• Determine algebraically the sum of two or
  more vectors by adding the components of the
  vectors.

In the words of Barton Micklus, "Why is it you never find time to do it right but always find the time to do it again?". This is the obvious evolution of physicsmainland twitter. This will allow for a more detailed and robust explanation of ideas concepts and assignments. I hope this will help you organize prepare and learn the material and concepts at hand. Please be patient and if you have any suggestions please feel free to pass them along.
