PHYSICAL SCIENCE

PHYSICAL SCIENCE

 physical science is an area of science that deals with materials that are not alive and the ways in which nonliving things work or in other words the study of laws os nature is called physical science.
It is again sub divided into
  1. classical mechanics
  2.  quantum mechanics
  3.  electricity part
  4.  optics
CLASSICAL MECHANICS

  Classical mechanics is concerned with the set of physical laws describing the motion of bodies under the action of a system of forces. The study of the motion of bodies is an ancient one, making classical mechanics one of the oldest and largest subjects in science, engineering and technology. It is also widely known as Newtonian mechanics. Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, such as spacecraft, planets, stars, and galaxies. Besides this, many specializations within the subject deal with gases, liquids, solids, and other specific sub-topics. Classical mechanics provides extremely accurate results as long as the domain of study is restricted to large objects and the speeds involved do not approach the speed of light.

branches of mechanics

  1. units and diamensions
  2. kinematics
  3. projectile motion
  4. forces
  5. newtons laws of motion
  6. friction
  7. work, power, energy
  8. circular motion
  9. center of mass, linear momentum, collisions
  10. rotational mechanics
  11. gravitation
  12. simple harmonic motion
  13. waves and sound
  14. magnetism
  15. fluid mechanics
  16. Heat and thermodynamics
In the next post i will write about each branch detailedly .SO STAY TUNED.......

DEFINITION OF SCIENCE

Science (from LATIN scientia, meaning "knowledge) is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
To understand what science is, just look around you. What do you see? Perhaps, your hand on the mouse, a computer screen, papers, ballpoint pens, the family cat, the sun shining through the window …. Science is, in one sense, our knowledge ,all the stuff that is in the universe: from the tiniest subatomic particles in a single atom of the metal in your computer's circuits, to the nuclear reactions that formed the immense ball of gas that is our sun, to the complex chemical interactions and electrical fluctuations within your own body that allow you to read and understand these words. But just as importantly, science is also a reliable process by which we learn about all that stuff in the universe. However, science is different from many other ways of learning because of the way it is done and the person who practices it is called a scientist. This blog will teach u what science  actually is.

There are many types of sciences like astronomy , philosophy , biology , physical science , chemistry , ecology , geology .... etc.These branches are subdivided. I'll tell all the branches i know below.
