TO hell WITH PHYSIcs.
just kidding. Im just taking my fustration out, thats all. This long test we had was a real ass kicker. I just dont know why i cant seem to understand the charge/electric field-force topic. I just really dont know. It wasnt like this in the radiation lesson. I got a high grade in there! But now, i lament at the corner for getting a 26/60 score... damn.
Oh well, life gets back at you, as some people say. We all have our times. And now is my time to sign out for now. I wonder if im still gonna update this blog... im starting to feel lazy XD

well remember my previous post, about the radioactive thingy being difficult? well scratch that. IT IS easy. dammit i cursed myself on not getting that...
Well i just wanna say thank you to a special friend out there. She helped me understand all those formulas XD.
Well, thats all folks.

WTF!! this was definitely the most difficult physics session to date! my mind just couldnt keep up with all the formulas involving radioactive decay and all that whatnot! i mean, my head was throbbing, literally!
well... atleast there was someone there to teach me. But still, with all the formulas and equations at my disposal, i couldnt help but secretly beg for mercy that this wont be repeated again.
now to look for that alaxan... its around here somewhere...

haha. i passed the physics test! wohohow. lucky me!
but there's still one more problem. my quizzes. theyre less than half the HPS.
Oh well... better start sucking up on my parents XD.
haha thats all for now. Happy vacation!

a certain classmate of mine said that the highest score in the periodic test for our section was 31... which means all of us failed.... ouch.
anyways the test was comparatively easier than the long tests. Easier to guess anyway. but still hard. we were lucky that we hav sci-cals with us XD.
well, thats all folks.

Concave and Convex. Diverging and Converging. Negatives and Positive signs. Magnifications and Focal lengths. Pls. no more...
Well to meet up with the requirements, i am
forced to write the steps in how to get the image in the convex and concave mirrors for the ray diagram...
For the Concave Mirror:
1. Prepare materials i.e. ruler, pencil and paper.
2. Draw a line and inscribe a circle of any length.
3. The Circle would be the mirror. Then divide the distance between the radius and the arc of the circle and mark it as the focal point.
4. Place the object in any location except for behind the mirror. [It is recommended that you place a tip of the object in the line]
5. Draw a line from the tip of the object parallel to the principal line. Once it hits the mirror, make the line pass through the focal point and extend as needed.
6. Make another line from the tip of the object passing through the focal point. Once it hits the mirror, it will bounce of and will be parallel to the principal line.
7. Draw a line that will pass through the radius.
8. The intersection of those line is the Image! Hooray!
For the convex mirror:
1. Repeat steps 1-4 for the concave mirror
2. Make a focal point and radius in the back of the mirror. Those will be our basis for the lines.
3. Repeat the construction of the lines, but this time the focal point and radius is in the back.
4. The image that will form is in the back of the mirror and is called a virtual image

wow. i thought the concave and convex mirror lesson was easy. Well it was easy in the drawing part, but when it came to the formulas, my head wont understand a thing....
lesson: formulas can cause brain damage.
