I thought I'd post this question for those even more scientifically
abled than I to explain:

How can a little kid (or an adult for that matter) sit on a perfectly
still playground swing, begin rocking back and forth, and within a
minute be wizzing back and forth to a pretty good height, without ever
touching the ground or other still grounded object?

Anyone who can supply their own answers, with equations if possible, is
welcome to reply...
