Motion studies as a field of physics deals with motion of atom and molecules of solids, liquids and gases along with various factors impacting the movements. As such numerous related concepts like elasticity, surface tension, stress and strain, viscosity and velocity affect motion to a great extent and needed deep examination. Concepts of heat, energy and temperature are part and parcel of the thermodynamics and have immense practical utility. In its vast domain, ...
Understanding of vectors and vector analysis is necessary in order to have proper grasp of phenomena related with motion dynamics in particles, rigid bodies and deformable bodies. In the case of velocity of particles, acceleration, motion laws, force, mass, motion under different situations, harmonic motion, vibration, work and energy are studied. In the case of rigid bodied, motion study deals with centre of mass, linear and angular momentum, inertia, ...
The science dealing with the properties and interactions of matter and energy, i.e., physics concerns itself with atomic structure among other things. The atom, the ether and electricity were firmly entrenched in the minds of physicists at the beginning of nineteenth century, but with the discovery of x-rays and a, B,y-rays the domain of optics, nuclear physics and astrophysics has grown tremendously explaining hitherto unexplained phenomena and making ...
This is the first monograph, ever written on the Pahari Korwas, a primitive tribe of Chhattisgarh, found in the north-eastern region of the state. This tribe has been notified and declared as one of the primitive tribes by Govt. of India during the Fifth Five Year Plan, when the strategy/concept of Tribal Sub-Plan (TSP) was conceived for the over all development of the Scheduled Tribes and the areas. It is now more than three decades that Pahari Korwas, one of ...
