Simple machines make our lives easier by changing the
amount of force or the direction of the force being applied (added). There are
four simple machines that we use most often in our lives.
An inclined plane is a slanted surface that helps to either lift up or lower an
object. Think of a slide. It is much easier to slide down when it is slanted than if
it was straight across. A lever moves around a point to increase or decrease the
amount of force. A pair of scissors has two blades connected to a point which
helps the scissors to move.
Another example of a simple machine is the pulley. A pulley uses wheels and
a rope to raise, lower, or move an object. Think of the American flag. When it is
on a pole, we pull a rope attached to wheels to help us move the flag to the top of
the pole. A wheel and axle also helps objects to move. The wheel and axle is a
wheel with a rod (axle) through the center. Some examples of wheels and axles
are bicycles, Ferris wheels, and wagons.
Simple machines do not change the amount of work we have to do. We would
still have to push the box in order to move it from one area to another. By using
simple machines to help, we are making our work easier!
