Chapter Three: Vectors and Two-Dimensional Motion I) Vectors A) Two vectors are equal if they have the same  magnitude  and the same  direction B) Components of vectors 1) A x  +  A y 2) A x  =  A  cos Θ 3) A A  sin Θ 4) ( A x 2  +  A y 2 ) 5) tan  =  Θ A y  /  A x C) Adding vectors: two or more vectors may be added if they all have the same  units 1) Geometrically a) Draw the first vest vector on a pair of axes using some scale and so its  direction is specified b) Draw the second vector using the same scale with the tail of this vector  starting at the tip of the first vector, it must be drawn along the direction  that makes the proper angel with the first vector c) Resultant vector is drawn from the tail of the first vector to the tip of the  second vector 2) Algebraically: using components a) R A B x b) R A B y c) R 2  =

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
