SYNTHETIC MATERIALS Polymer:-   A  polymer is made of small units.The monomers combine end-to-end under certain condition to form a polymer. For example cellulose is a polymer of glucose while hemoglobin is a polymer of amino acids. Polymerization :-                                      The process of formation of polymer from a monomer is called polymerization. Polymers can be classified into three types ·          NATURAL, ·          SEMI- SYNTHETIC ·          SYNTHETIC   TYPES OF FIBRES Fibres are also Polymers, so they are of above three types. TYPES OF FIBRE EXAMPLES Natural Cotton, jute, Silk, wool Semi synthetic Rayon (viscous, cuprammonium and acetat...

MOTION LEARNING OBJECTIVES          After a study of the chapter, the learner will be able to • Distinguish between uniform and non-uniform motion using the graphical method. • Calculate numerically value the displacement, velocity, or acceleration using an equation of motion. Appreciate that uniform circular motion is accelerated motion. • Identify the given physical quantities as vector or scalar. • Explain that motion is relative in nature. Motion forms an integral part of our life. All microscopic and macroscopic objects in-universe show some kind of movement. All of the objects such as planets, moons, etc. It also exhibits motion.                                All these examples can be clearly understood and discuss if we can describe motion, its property, and other related aspects such as...
