A simple machine is what it says, it's a very simple machine, made up of only one simple machine, such as a screw or a lever. A complex machine is more than one simple machine working together, instead of working alone.Simple machines are:ScrewInclined PlaneLevers (three different classes)PulleysWheel and AxelWedgeExamples of compound machines:DrillScissorsA simple machine has 1 part, while the complex machine is made up of many different parts.SIMPLE MACHINE : I machine that is simple and small most of the time .COMPLEX MACHINE : a machine that's complex .a simple machine makes the amount of force and effort you use in work easier.a compound machine is a numerous amount of simple machines put together to make work easier.a simple machine is one of the basic machines: wedge, lever, inclined plane, pulley, or a screw. a complex machine is any two or more of these used in collaboration.Complex machines are simply a series of simple machines working to achieve a single goal.
