PHY 2053 Discussion  Review: Chapter 3  1. Vectors 1) Two properties and two operations of vectors:     Properties:   Magnitude & direction    Operation: Addition & scalar multiplication 2) How do you express a vector graphically, its magnitude and direction?     We use an arrow with its length proportional to the magnitude; The orientation of the   arrow represents the direction of the vector. 3) How do you express a vector  A  algebraically, its magnitude and direction?     We use components A (=Acos ) and A θ y.  (=Asin ).  θ    Magnitude: A =  (A x ² +A y ² ), Direction:   = tan θ ¹ (A y /A x ) 4) Graphical method to express A ± B: A+B: Place the tail of B at the head of A; A+B is the arrow drawn from the tail of A   to the head of B A-B: Place both tails together; A-B is the arrow drawn from the head of B to the head   of A.

    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.
