Can't read Legend on green easily.
Remind me why I should care about this.

more than two atoms in a closed system, the graphs for the kinetic energy
and the potential energy become irregular and difficult to predict. By a
closed system, we mean that the system is completely isolated fromthe rest

starting with different amounts of kinetic and potential energy. Run the

apply here.<br><br></font><b><font size="3" face="Verdana, Arial, Helvetica, sans-serif">In
