PH1110 Notes Vectors –  Ch 1  Sec 7,8,9 1.7 Vectors and Vector Addition Velocity has a speed and a direction Scalar Quantity-  when a physical quantity is described by a single number Vector Quantity-  has both a  magnitude  (the “how much” or “how big” part) and  a direction in space. Displacement-  is simply a change in position of a point Vectors are in boldface italic type with an arrow above them If 2 vectors have the same direction they are parallel, if they have the same  direction and magnitude they are equal. Negative of a vector-  when vectors have the same magnitude but opposite  direction Anti-Parallel Vectors-  when two vectors have opposite directions, whether their  magnitudes are the same or not. Magnitude is represented by light italic type with no arrow on top The magnitude  of a vector quantity is a scalar quantity and is always positive
