Learn the basic concepts of physical and chemical sciences. Time, space, position, distance, co-ordinate systems; matter and atomic theory (atoms, molecules, elements, compounds, solids, liquids and gases); energy (conservation, potential and kinetic, heat, work, machine); waves and vibrations (wave motion, reflection, refraction, interference, amplitude, wavelength, frequency); force and motion (speed and velocity, gravity, Newton's laws); basic electricity concepts (static, charging, currents, circuits, Ohm's Law, voltage, resistance, watts, efficiency, alternative sources). Discover! Physical and Chemical Sciences features over 130 screens of text and graphic illustrations, over a dozen interactive exercises, more than two dozen video clips, and a half-hour video documentary -- Aircraft and Spacecraft, an exciting look at the practical uses of Physical and Chemical Sciences in NASA's air and Space Program, and an exploration of how new materials technology development is revolutionizing the world of science and technology.
