Steps in Component Method

1. Draw each vector and show its components.
2. Determine the magnitude and direction of the components by using the trigonometric functions.
3. Find the sum of the x-components.
4. Find the sum of the y-components.
5. the answers obtained in steps 3 and 4 are the x and y components of the resultant vector. Use these components to find the magnitude and the direction of the resultant vector, using the Pythagorean Theorem and the Trigonometric Functions.
6. Check your answer by comparing it with the result obtained in Graphical Method (optional).
   

Steps in Graphical Method

1. First, choose an appropriate scale and coordinate system for the given vectors.
2. Draw the first vector starting from the origin of the coordinate system. Draw the second vector starting from the head of the first vector. Proceed to draw the remaining vectors starting from the head of the most recent vector drawn. All vectors must be connected in series, head-to-tail fashion.
3. Draw a new vector connecting the tail of the first to the head of the last vector drawn. the new vector is the resultant of the given vectors.
   

Resultant Vector

Scalar Quantities can be addedand subtracted like ordinary numbers provided the scalars have the same units. For vectors, the sum depends on the direction of the vectors. The sum of two or more vectors is represented by a single vector called the Resultant.

I'm happy in my Physics class because when we are about to take a test for the second time around, sir Mendoza did help me to answer my test, i asked him about how to solve for the direction of the vector that is needed to that problem and he helped me, im so happy of that because i got a high score in that test because he explained to me how to do it. hehe!

About Me...

I'm Jayvee D. Tabal of III-Ptolemy, Manila Science High School, 14 yrs old

I'm part of the Manila Science High School Chorale coz' my favorite hobby and my talent is singing

Mathematics and Chemistry are my favorite subjects, I also like Physics but it is quite hard

I am more enhanced in Philippine language compare to English so I can say to myself that I am a Great Filipino Citizen and I am proud of it

I like teachers who are friendly to students and considerate like Mr. Mendoza and also with a right outlook in life

When i saw before Mr. Mendoza, i taught he is a simple one but then i finally found out that sir is scary because he is very strict and miticulous. Even if he has that trait, he is a friendly and considerate. I hope it will not last so that me and my classmates will not be scared with him.
