The Meaning Of Symbols In Physics - And How To Read

Physics Problems And Solutions - In Physics, many symbols are used; both Latin letters in uppercase in Physics and lowercase in Physics including Greek letters.

THE MEANING OF SYMBOLS IN PHYSICS - AND HOW TO READ

A. Latin letters:

  • The uppercase A in Physics are used for symbols for electric current units, namely Ampere (A) while lowercase letters in Physics are used for symbols for acceleration (a).
  • The uppercase B in Physics are used for magnetic induction field symbols (B)
  • The uppercase C in Physics, the unit of electric charge is Coulomb (C); while the lowercase c in Physics is used to symbolize the speed of light (c = 3 x 108 m/s)
  • The uppercase D in Physics is used to symbolize the electric field displacement (displacement), while lowercase letters in Physics are used to symbolize distance (displacement).
  • The uppercase E in Physics is used for symbols of Energy, Electric Field, while lowercase letters in Physics are used for symbols of electron charge (e=1,6x10-19 C)

  • The uppercase F in Physics is used for the Force symbol, while the lowercase F in Physics is used for the frequency symbol.
  • The uppercase in Physics is used for the symbol for Newton's gravitational constant while lowercase in Physics is used for the symbol for acceleration due to gravity.

  • The uppercase H in Physics is used for the symbol for the magnetic field due to electric current, the Henry unit symbol for inductance, while the lowercase h in Physics is used for the Planck constant symbol.
  • The uppercase I in Physics is used for the symbol Electric current, Intensity.
  • The uppercase J in Physics is used for the Joule symbol, the unit of energy and also for the symbol for electric current density.

  • The uppercase K Commonly used in lowercase letters in Physics as a constant, eg Coulomb's law of static electricity constant, Boltzman constant of thermodynamics.
  • The uppercase L in Physics is used for the symbol for angular momentum, while the lowercase L in Physics is used for the orbital quantum number symbol and is used for the symbol for length.

  • The uppercase M in Physics is used for the magnetization symbol, while the lowercase m in Physics is used for the mass and meter symbols.
  • Uppercase n in Physics is used for the Newton symbol, the unit of force and also the symbol for the number of particles, while lowercase n in Physics is used for the main quantum number symbol.

  • This O is not used, except for capital letters in Physics for the symbol for the 5th shell of the electron path. ask why?
  • The uppercase P in Physics is used for the power symbol, while the lowercase p in Physics is used for the pressure symbol; electric polarization; electric dipole moment and linear momentum.
  • The uppercase Q in Physics is used for the thermodynamic heat symbol, while the lowercase q in Physics is used for the electric charge symbol.
  • The uppercase R in Physics is usually used for the radius of a circle (radius) and distance (range).

  • The uppercase S in Physics is used for the entropy symbol, while the lowercase s in Physics is used for the second and spin quantum physics symbols.
  • An uppercase T in Physics is used for period symbols; temperature, the unit for Tesla's magnetically induced field (T), while the lowercase t in Physics is used to represent time.

  • The uppercase U in Physics is used for the Energy symbol
  • Uppercase V in Physics is used for symbols of magnitudes and units of electrical voltage (Voltage and Volts) and potential in general, while lower-case v in Physics is used for symbols of velocity.
  • The uppercase W in Physics is used for the symbol for Work and Watt for the unit of power.

  • Z together with Y, Z is used for coordinates
  • Y for Young's modulus;
  • Z nuclear physics, states the number of protons in the nucleus.

B. Greek letters.
  • $\alpha$ (alpha): symbol for Alpha particles or Helium nuclei and also denotes angular acceleration in circular motion.
  • $\beta$ (beta), $\gamma$ (gamma): Types of nuclear radiation, together with .$\alpha$ in special relativity, $\gamma$ stands for Lorentz factor.
