Mechanics deals with all kinds and complexities of motion. Mechanics is the oldest branch of physics. The oldest known human DNA, which may belong to a mysterious branch of humanity, reveals human evolution was even more confusing than thought, researchers say. Physics is a branch of science.It is one of the most fundamental scientific disciplines.The main goal of physics is to explain how things move in space and time and understand how the universe behaves. The word physics comes from the Greek word ἡ φύσις, meaning "nature". The formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. His work in ancient physics spread around the known world and was the major conduit through which the knowledge of the Greeks passed on to the great Islamic scholars of the medieval period. Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions). It includes various techniques, which can simplify the solution of a mechanical problem. Branches of astronomy. 1 MOTION Motion, more properly called "mechanics," is the oldest branch of physics, having been put on a firm quantitative basis by Isaac Newton (1642-1727) who by the age of 24 had also developed calculus, which subsequently became an indispensable tool of science. It studies matter, forces and their effects.. A brief treatment of kinematics follows. Physics is the branch of science which is concerned with the nature and properties of non-living matter and energy that are not dealt with by chemistry or biology, and the fundamental laws of the material universe. It is the oldest of the physical sciences, is the study of the motion of objects. The branch of science that deals with the study of the motion of the body, its causes, and its effects. What is mechanics in physics? Motion in One Dimension. Astrobiology – studies the advent and evolution of biological systems in the universe. ; Astrophysics – branch of astronomy that deals with the physics of the universe, including the physical properties of celestial objects, as well as their interactions and behavior. Astrophysics is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. As such, it is a huge and diverse area of study. For full treatment,
