How do I change the amount of whitespace between sections in Latex?

Question

How do I modify the distance between the end of a section and the header of the next section in a Latex document?

Answer 1

You can configure the style of section headings, including spacing, using the titlesec package. There's a 'compact' option for simple reduction of space, or you can specify specific values using the more advanced options (see the documentation on the linked page for the gory details).
