what happened?
the weeks start to become stressful...
the lessons are starting to become coplicated
and i'm starting to fail...
physics class s starting to become exciting...[because of the calling of parents for failing students...]
the lesson on wave confused me...i got low grades again in the test...getting the appropriate formula to use was my problem...[i shall try to practice...] [ill make up for the low grades..hopefully]
the lesson on destructive and constructive wave was great especially that it was simple but looked complicated...
moral of the story:practice makes perfect...

getting the resultant vector using component method/graphical method
component method:
1. you need to get the data needed, you can make it organized by using a table.
2. get the resultant component by adding up all the x-components and adding up all the y-components. [Rx=Ax+Bx+Cx ; Ry=Ay+By+Cy]
3. add the square of the resultant component. [ (Rx)2+(Ry)2]
~~~
graphical method:
1. draw a cartesian plane to easily determine the horizontal and vertical.
2. decide on a scale to use.
3. draw each vector on the cartesian plane.
4. connect the point of origin to the ending point.
5. measure the line connecting the point of origin to the ending point.
6. convert the measurement using the decided scale.

Did I learn/understand anything in Physics[?]
1st weeks...
What a nice triangle [drawn by me via paint] Labeled it according to what/how our teacher, Mr. Mendoza taught us..... drawing this triangle helped me answer the tests even though i got a:
On the first and second activities [wait...one was a quiz right]
...
Knowing our teacher, Mr. Mendoza doesn't like giving considerations...
I was forced to be serious at the time...[don't want to lose some of those precious allowance]
Hopefully in the next activity [or was it a quiz] i was able to answer the first question correctly [don't know if I was just lucky that day...]
Moral of the Story: Don't depend on considerations...[and study your lessons]
