A line is a set of points described by an equation which may be written in the form y=mx+b where the constant m is the slope of the line and b represents its y intercept. As x varies y varies. In the figure above, as the temperature (T) of the system varies, the kinetic energy (E) of the molecule varies. The line describes the equation E=kT where k is the slope of the line.

The set of points which satisfy the equation y=1/x is a hyperbola. As x varies y varies inversely. As x becomes smaller y becomes larger. The movie above shows two particles of opposite charge attracted to each other. The relationship between coulombic energy and distance is an inverse relationship. The coulombic energy between the two particles varies with -1/r, where r is the distance separating their center of masses. In the movie notice that as r gets smaller, the potential energy becomes more negative.

The movie above shows that the torsion bond energy of a molecule can be modeled by a periodic function.
