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.
No. Gears are a type of simple machine. Combined with another simple machine, it would then make a compound machine.

A knife is not classified as a compound machine; it is a simple machine. Specifically, a knife functions as a wedge, which is one of the six types of simple machines. While a compound machine consists of two or more simple machines working together, a knife operates on the principle of a single wedge to cut through materials.

A zipper is a compound machine that functions as a series of simple machines working together. It typically consists of two flat metal pieces with interlocking teeth that are pulled together and apart by a slide mechanism. The teeth act as inclined planes that wedge together when the slider is moved up, and apart when moved down, allowing the zipper to open and close.
its a compound machine
Its a simple machine machine i could see where your coming from thinking it is a compound machine. But i mean it is simple. Now i know a couple stores have compound machine
Well, the simple machine eats up the little pegs it is connected to and walah the zipper works.
compound machine
no
No, its a simple machine.
yes
Anything with more than one simple machine in it is a compound machine. Since Wheelbarrows have both wheel-and-axle(one simple machine) and levers(Another simple machine), the wheelbarrow becomes a compound machine.
