SUMMARY
The net force applied on a dam by water can be calculated using the formula Fnet = pgd * w * d, where p represents the density of the water, g is the acceleration due to gravity, d is the depth of the water, and w is the width of the dam. The hydrostatic pressure equation, P = p_0 + pgd, indicates that atmospheric pressure (p_0) cancels out since it acts equally on both the dam and the water. This results in the net force being dependent solely on the water's density, depth, and the dam's width.
