Simple Machines

 Simple machines are used to move heavy objects, carry objects, and attach objects together. 

There are six simple machines;

One of the simple machines is a wheel and axle is used to move objects around easier it redues the amount of force needed to push by making something roll. 

Another simple machine is a pulley, a pulley is used to move heavy objects from a low level to a high level it reduces the amount of force needed to lift heavy obejects by sharing and dividing the force out. 

The third simple machine is a wedge the wedge is used to push things apart. It changes the directions of the force to go sideways. 

The fourth simple machine is a screw a screw is used to attach objects to other objects. This machine works by making objects twist around the machine. 

The fifth simple machine is the lever the lever is used to lift heavy obejects it changes the imput force by using a pivot and a bar. This machine can also be used to mesure forces like  weight.

The last simple machine is aattach inclined plane the inclined plane is used to move objects from a low level to a high level more easily. 

These are all still used today to move objects.
