The Physics Card is a ultra-fast, easy to use, plug-in card for the HP 48 GX/SX, and an invaluable aid in solving a variety of practical problems encountered by students and professionals alike in physics. Designed for speed, accuracy, and ease of use, this "plug and play" software gives the user the ability to find "quick" solutions to common sets of problems. It is akin to carrying a full set of "solutions in your pocket".

Product Description

Main Features

Over 300 equations, several integral tables, a powerful
polynomial solver, reference formulas and data, Taylor expansion, and vector analysis.

Easy entry of values for variables (with units) using the
menu keys provided. Effortless solving and converting of units.

Menu can be displayed in a large or small font.

The user interface browser presents eight categories: A
constants library, an equation library, integral tables, a polynomial solver, reference
data, reference formulas, Taylor expansion, and vector analysis. The top level interface
browser for the equation library presents 11 categories, and each category has many
sub-categories. For example, the optics category has six sub-categories (see below, far
right).

Main Level Browser Equation Browser Sub-Categories in
Optics

Equation sets in a given sub-topic can be solved as a
whole, or as a selected set of equations. The variables can be entered with units,
variables in the equation sets have descriptions in addition to names, and often an
equation set will have an associated picture. The results of computations can be plotted
using the plotting routines as soft keys, allowing graphical evaluation of step-wise
changes in key variables.

Constants Library

45 constants are incorporated into the physics card for
quick reference. They include general constants, such as Napier and Euler constants, and
golden ration, as well as universal constants such as gravitational constant, permittivity
and permeability of free space, properties of electrons, protons and neutrons, standard
temperature and pressure, molar volume, Avogadro’s number, electronic charge and
mass.

Electrical Circuits - Capacitor basics, cylindrical,
spherical and parallel plate capacitors, current and voltage dividers, inductor basics,
solenoids and toroids, Ohm’s law, resistor basics, and transformers.

Electric Fields - Coulomb’s law, dipole, disk and
line charge, Lorentz force, ring, sheet, and surface charge.

Forces/Energy/Work - Angular forces, Coulomb’s law,
drag force, frictional forces, gravitational forces, Hooke’s law, linear forces, and
Lorentz force.

Gravitation - Escape velocity, gravitation, free falling
object, circular and elliptical orbits, projectile motion, and terminal velocity.

Linear Mechanics - Center of mass, elastic and inelastic
collisions, linear mechanics, and rocket science.

Optics - Brewster’s Law, reflection and refraction,
spherical mirrors, thin lens, and two-slit diffraction.

Oscillations - Mass-spring system, simple, torsional and
conical pendulums, simple harmonic motion, and two body system.

Special Relativity - Doppler effect,
energy/mass/momentum, Gallilean and Lorentz transform, and length/time dilation.

Waves - Doppler effect, organ pipes, sound waves, and
waves.

Integral tables

This category includes nearly 100 integrals organized in 6
categories: user-defined, rational, irrational, trigonometric, hyperbolic, exponential,
logarithmic, and definite integrals.

Polynomial Solver

Solves a polynomial of arbitrary order with real or complex
coefficients, and computes all results-- real and complex.

Reference Data, Formulas

Includes SI prefixes, Solar System data, Greek alphabet,
formulas for moments of inertia, centroids, trigonometric relations, definitions, and
pictures.

Taylor Expansion

Expands arbitrary functions about an arbitrary point of
reference.

Vector Analysis

Includes common formulas for dot and cross product, del
operator, gradient, divergence, curl and the Laplacian. These have corresponding
programmable commands with results available symbolically or numerically,
and in rectangular, cylindrical, and spherical coordinate systems.
