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
