A comparison of thermal energy (red; Equation 15), kinetic energy(blue; Equation 14), gravitational potential energy (purple; Equation 16), magnetic energy (turquoise; Equation 17), and total energy (black; Equation 18) for several of the small clouds. Note that the purple line plots the negative of the gravitational energy while the total energy accounts for the sign of the gravitational energy. The left panel shows the S-nojet1 run with solid lines and two of the runs with default jet parameters (S-jet1 and S-jet3) with dashed and dotted lines. The right panel shows the two runs that form a massive wind star early in the run, one with (S-jet2; dotted line) and one without (S-nojet2; solid line) jets. The massive wind stars significantly alter the subsequent progression of each run and so we consider these runs separately. In both panels, negative values implying gravitational boundedness are shaded gray.
