Physics describes the world around us. In mechanics we study the motion of objects and the related
concepts of force and energy. It takes two qualities: size and direction, to describe force and motion. A
vector is such a quantity that has both magnitude and direction. Vectors are not Physics but vectors form a
very important part of the mathematical description of Physics. In this section, learners will develop the
understanding of the concepts of vectors. They need to master the use of vectors to enable them to describe
physical phenomena (events).
