Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.

for me, the spoon is a simple machine. because it is use to eat. a spoon is useful to eat.. only that if it is a compound machines it can use as many.. in compound machines it can be use as many things...
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.

A simple machine typically uses one movement to accomplish its intended task. Examples of simple machines include levers, pulleys, and inclined planes.
What are three simple machines that are basically the same?
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
Grasshoppers have TWO COMPOUND EYES AND THREE SIMPLE EYES.
Three types of screw machines are used by manufacturers: swiss, single-spindle, and multiple-spindle machines.
The six simple machines are wedge, inclined plane, screw, the wheel and axle,lever and the pulley are the six simple machines. The inclined plane (you'll see why I started with this first) is simply a ramp or slope that reduces the amount of effort force needed to move the load. The wedge is two inclined planes put together back-to-back. A screw is an inclined plane wrapped around a rod. The wheel and axle is a circle attached to a rod. A lever is a simple machine consisting of a rigid bar pivoted on a fixed point, called the fulcrum, and used to transfer the effort force in order to raise the load. There are three levers: Class 1,2,and 3. Last but not least, the pulley is a grooved wheel with a rope or chain running through it. There are two types of pulleys: fixed and moveable. There are two systems, both consisting of pulleys: the block and tackle and compound pulley. Hope this helped!
