y'' + gy' + y = 0(So g is the damping constant, instead of gamma, and the mass and spring constant are both 1: m=1 and k=1.)
Here is a picture showing the different sorts of equations:
.
In the underdamped case, the damping constant g is
between 0 and 2; here are graphs for some of those values.
Notice that as g increases and approaches 2, the
oscillations decay more quickly, and also the frequency drops.
.
In the overdamped case, the damping constant g is
bigger than 2; here are graphs for some of those values. There
are no oscillations. As g increases, the graphs
decay more slowly.
