due to lack of access to the net I found it very hard to post my articles here regularly.
we had our very first long test and I've got 18 / 75. whoa! imagine.. a mascian can't even manage to get half of the target score.
we are now currently discussing mirrors, reflection, optics which is another source of problem. and this monday we'll have again this bloody test which I guess will have a part 2 like what we did last long test. :]

Graphical and Component Method are used to get the Resultant Vector. Here are some steps to get the Resultant Vector by using the Graphical and Component Method.
Steps Using Graphical Method:
1. Please make use of a cartesian plane to serve as the origin.
2. Get the vectors. Make a scale first so that you will not confuse regarding measurement, example 30 meter=1cm
3. Plot now the first vector. Connect the first vector from its tail up to the head of the first vector then do the same thing to the succeeding vectors.
4. There are given formulas so it is now easy for you to calculate for the resultant vector.
5. Pythagorean Theorem = Magnitude . Tan Function = Direction.
Steps in using the Component Method:
1. Plot a Table.
2. Then get the values of each component by using cosine for x and sine for y.
3. After getting the values, get the sum of each component.
4. Square each sum the add the squared value.
5. After getting the sum get the square root.

lab physics. :] Expectations:
Lesson:How I wish that the lessons would be easier for me. Because last year was no application for me. So, I hope that my expectations would come true. I'm now a third year student which is considered the hardest part in the high school life some I am now ready to the challenges to be given to me.
Teacher:Hmm. I don't know much about him. But, when I will compare him to the other teacher in Physics I know that he is
quite better but teachers has their own way in enriching students minds. :]
First Post. Just a Trial.
