Unformatted text preview: al quan##es. Looks like in order to describe force, we need to specify its direc#on as well. Direc#on has no rela#on with mass. Addi#on of force may require more maths in order to incorporate direc#ons. Vectors (contd…) •  The quan##es like mass can be specified my their magnitude alone and are called scalar quan##es or simply scalars. Other examples are distance, speed, density, volume, pressure, etc. •  Quan##es like force cannot be completely described by magnitude alone. They need direc#ons as well. Such quan##es are called vector quan##es or simply vectors. Other examples are displacement, velocity, accelera#on, momentum, electric field strength, magne#c field strength, etc. •  Vectors quan##es are denoted by bold face leXers in prints and in hand ­ wri#ng it is usually denoted by ufng an arrow over the symbol. Thus p force may be denoted b...
