This unit includes the importance of universal standard units of measurement, applications of dimensions and vectors in the study of physics. The physics scope, need of measurement, concept of motion and rest, cause of motion and different types of motion are also included with the help of daily life examples. Significance of gravitation, concept of work and energy are also highlighted. The basics of the motion of a rigid body and the significance of rotational motion in day to day life have been explained.
