Basic principles of physics  [edit]

Physics  is with Mathematics and Chemistry one of the "fundamental science" because the other  natural sciences  (biologygeology, etc.) deal with systems that obey the laws of physics.

The physical laws of  matterenergy, and the  forces  of nature govern the interactions  between particles (such as  moleculesatoms, or  subatomic particles). Some basic parts of physics are:

  1. Matter principles
  2. Forcesweight, and  mass
  3. The  theory of gravity
  4. Energy
  5. work, and  power
  6. Energy forms
  7. Energy conservationconversion, and transfer.
  8.  Energy source  the transfer of energy from one source, to work in another.
  9. Movement  
  10. Describing and measuring  motion
  11.  Newton's laws of motion
  12. Momentum  and  conservation of momentum
  13.   Motion, position, and  energy
  14.  Energy  and  heat
  15.  Heat flow:  conductionconvection, and  radiation
  16. Temperature  and  thermometers
  17.  The three  laws of thermodynamics
  18.   Phases of matter  and  phase transitions
  19.  Kinetic molecular theory
  20.  The principles of  waves  to explain the properties of sound  and of  light
  21.  The principles of  electricitymagnetism, and  electromagnetism
  22. Basic principles of astronomy  [edit]
  23. Astronomy  is the  science  of celestial bodies and their interactions in space. Its studies includes the following:
  24.  The life and characteristics of  stars  and  galaxies
  25.  Origins of the universe. Physical science uses the  Big Bang  theory as the commonly accepted scientific theory of the origin of the universe
  26.  A  heliocentric  Solar System. Ancient cultures saw the Earth as the centre of the Solar System or universe (geocentrism). In the 16th century, Nicolaus  Copernicus  advanced the ideas of heliocentrism, recognizing the Sun as the centre of the Solar System.
  27.  The structure of  solar systemsplanetscometsasteroids, and  meteors
  28.  The shape and structure of Earth (roughly spherical, see also  Spherical Earth)
  29.  Earth in the Solar System
  30.  Time measurement
  31.  The composition and features of the  Moon
  32.  Interactions of the Earth and Moon
  33. (Note: Astronomy should not be confused with astrology, which assumes that people's destiny and human affairs in general are correlated to the apparent positions of astronomical objects in the sky -- although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not.)
