A plane has length and breadth. It has two dimensions. Any flat surface is a plane. In our study, we deal with figures drawn on plane surface..

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynamics. In this chapter..

Summary - Movements and locomotion takes place as a result of co-operation between the muscle and skeletal system, hence the study of both is necessary. Skeletal system in humans is formed by bones and cartilages. It helps in protection of delicate visceral organs, mechanical support, mov..

It is a common observation that density of ice is less than that of water because of which ice always floats over water. Moreover, it is a known fact that density of water is maximum at 4C. Ice is lighter than water: X-ray studies have shown that in ice, four hydrogen atoms tetrahedrally ..
