Yayayay...... Haha... Hayy... I'm still not finished with editing my blog because i'm too bored to do it... Ahehe... Maybe i'll just find the time when i can really edit it... And... I'm still thinking of what song should rily fit for our project... Maybe i'll find some songs later and i will make it na... So that we will finish our project early... Hehe... *And here are the vectors that we learned all about*... ^_^

Basic Vector Operations


Both a magnitude and a direction must be specified for a vector quantity, in contrast to a scalar quantity which can be quantified with just a number. Any number of vector quantities of the same type (i.e., same units) can be combined by basic vector operations.



Graphical Method:








Adding two vectors A and B graphically can be visualized like two successive walks, with the vector sum being the vector distance from the beginning to the end point. Representing the vectors by arrows drawn to scale, the beginning of vector B is placed at the end of vector A. The vector sum R can be drawn as the vector from the beginning to the end point.
The process can be done
mathematically by finding the components of A and B, combining to form the components of R, and then converting to polar form.




Component Method:






Finding the components of vectors for vector addition involves forming a right triangle from each vector and using the standard triangle trigonometry.
The vector sum can be found by combining these components and converting to polar form.
