  • Page 1 HP 30S Using the Built-in Physical Constants The CONST Menu Practice Solving Problems Involving Physical Constants...
  • Page 2 The CONST menu The HP 30S provides twelve physics constants that can be used in calculations and included in your programs. All the constants are expressed in SI units, but only the values are present. For example, for the speed of light, the built-in value is 299792458 which is in m/s, even though the units are not stated.
  • Page 3 š<<<<</š@@@@@@yy Answer: mP/me = 1836.152663. Compare it with the value on the HP 48GX (1836.152701) and the one calculated on the HP 33S (1836.1526633). Greater accuracy in measures implies new standard values. Constants are not that constant after all! Example 3: Einstein observed that any change in mass implies a change in energy and vice versa.
  • Page 4 (Note that it does not depend on the mass of the satellite). The period can be calculated as follows: 2xp8u6—U3/rš@@y*5.98u24 Answer: 7117.110266 s or 2 hours approximately. hp calculators - 4 - HP 30S Using the Built-in Physical Constants - Version 1.0...
