Friday, June 29, 20071. by looking at the fgure given, make a right angle that enclosed each vectors.
2. Then, depending on the given values, perform the trigonometric functions (SOHCAHTOA).
3. You can now solve for the value of x and y component.
4. To get the resultant vector simply add all the x-components of the vectors and all the y-components of all the vector.
5. Using the x and y components compute the magnitude of the resultant vector by using the Pythagorean Theorem then the direction will be given by any of the trigonometric functios.

1. Decide first the scale of given measurement to be use.
2. Then, start graphing the 1st vector with its origin and head, and label it.
3. Then, start graphing the 2nd vector at the head of the 1st vector.
4. If there is more than two given vectors just follow the head-tail pattern in graphing it.
5. Then, connect the origin of the 1st vector to the hed of the last vector. That line is now the resultant vector.
6. Then, using a ruler measure the length of the resultant vector. Using the scale, convert the length to its original unit. That length of the resultant vector will be the magnitude.
7. Using a protractor, measure the angle form, then this angle will be the direction of the resultant vector.
It may be simple yet COMPLICATED.

I really love the quiz in pHysics if it is all about DEFINITIONS..>>
I hate Computations>>>
So, I do hope that my teacher would always give us a quiz like that. So, i could pass this subject.

Saturday, June 16, 2007WhaT????!
i'M reaLLy disappointeD to my scores in our tests...
its really harD! almosts all of us gOt loW scOres...
I'm starting to hate PhySics but i caN't do anything... anD the worst thing is this is jUst the STaRT!!!
hmPP...
The onlY thing that i CaN do Know is to STUDY HARDER!...
well...

Saturday, June 9, 2007When I hear the word "Physics" the only word that strike in my mind is difficult. Yes, I always think that this subject is really hard! Its because, numbers is involve.
Well, I realized that numbers are not monsters so I'm not afraid. I always believe in myself. I will do my very best, just to pass this subject.
Easy or not, I know I can do this. I hope i could cope and understand the lessons. I' m wishing that this impression won't last.
