relative wavelengths, energies, and frequencies;
units of mass, distance, density, velocity, acceleration, energy,
force, power (luminosity), temperature, and frequency;
the three temperature scales in common use, and the boiling and freezing
points of water in each;
what weightlessness is; what causes a) a continuous spectrum,
b) an emission line spectrum,
