List four forms of energy that you use from morning, when you wake up, till you reach the school. From where do we get these different forms of energy? Can we call these ‘sources’ of energy? Why or why not?
Here we take up the scalar product of two vectors. The scalar product or dot product of any two vectors A and B, denoted as A.B (read. where θ is the angle between the two vectors as shown in Fig. 6.1(a). Since A, B and cos θ are scalars, the dot product of A and B is a scalar quantity.
In this unit, we will learn more about these three physical states of matter particularly liquid and gaseous states. To begin with, it is necessary to understand the nature of intermolecular forces, molecular interactions and effect of thermal energy on the motion of particles because a balance between these determines the state of a substance.
