Program: Constant By: Ben Axelrod This program fills up the variables with physical constants that science classes use frequently. There are 15 constants in SI units, and gravity is also given in English units. The program displays two screens with the names of the constants and what they are saved as. Feel free to edit this program and add some of your own favorite constants. Here is a list of the constants included: Usual Symbol Name Stored as Value and units ------------------------------------------------------------------------------- c Speed of Light C 299792458 m/ s Mu o Permeability of Vacuum M 1.256637 E-06 N/ A^2 Epsilon o Permittivity of Vacuum E 8.854188 E-12 F/ m G Newtonian Gravitation Constant G 6.67259 E-11 m^3/ kg s^2 h Planks Constant H 6.62608 E-34 J s h bar h bar (h/2Pi) I 1.054572 E-34 J s e Elementary Charge J 1.602177 E-19 C Na Avagadro Constant N 6.022137 E+23 atoms/ mol F Faraday Constant F 96485.309 C/ mol R Molar Gas Constant R 9.31451 J/ mol K k Boltzmann Constant K 1.380658 E-23 J/ K eV Electron Volt V 1.60217733 E-19 J u Atomic Mass Unit U 1.6605402 E-27 kg g Standard Gravity Acceleration D 9.80665 m/ s^2 g Standard Gravity Acceleration S 32.174 ft/ s^2 C Coulomb Constant L 8.99 E-09 N m^2/ C^2 -------------------------------------------------------------------------------- Questions or comments?
