What do all simple machines have in common?

All simple machines have the following properties:

They make work easier by changing the direction or magnitude of a force.

They have no source of power themselves. They rely on an external force, such as a person or a motor, to operate.

They have limited movement and are designed to perform specific work.

They do not create energy; rather, they transfer it from one place to another or from one form to another.

They are based on fundamental mechanical principles, such as levers, pulleys, inclined planes, screws, and wedges.

These properties apply to all simple machines, regardless of the specific type of machine. Simple machines are the building blocks of more complex machines, and understanding how they work is important in understanding how more complex machines function.
