A zipper is considered a simple machine because it primarily consists of two rows of interlocking teeth and a slider that brings them together or separates them. It utilizes the mechanical advantage of levers in the slider to open and close, but it does not combine multiple machines or mechanisms to perform its function. Therefore, it does not qualify as a compound machine.
A zipper is a compound machine that functions as a series of simple machines working together.
