2. Simple Machines
Simple Machines are Pulley, Wedge,
Lever, Wheel and Axle, Inclined Plane,
Screw And Gears.
These Machines help us do our work a lot
3. Examples of Simple Machines
This machine is called
the wheel and axle. The
wheels help people move
around with the chair
quickly and with less
force. While the chair is
moving,the wheels are
rotating around their own
axle. This one is located
inside my room.
4. Another Example
This is a staircase, Staircases
help us move from one level to
another. A staircase is an
inclined plane, you move up
and down over a greater
distance and greater force as
opposed to jumping up or
falling down a level of a house,
which will take a longer time
and greater force. This
staircase is located in my
house next to the living room.
5. Compound Machines
A compound Machine is anything that has
two or more of the six simple machines.
Compound Machines help us do our work
6. Examples of Compound
A stapler is a compound machine.
It is made up of two Simple
Machines, Wedge and Lever. The
staples in a stapler are wedges
because they pierce through
papers. The top arm of the stapler
is a Lever, it has a fulcrum or a
pivot point, which allows the top of
the stapler to move up and down.
When you put energy on this
lever, it transfers energy into a
staple, which staples the paper.
This stapler is located in the living
7. Another Example
This can opener is made up of 4
simple machines. First is the
wheel and axle which is the
handle, when you turn the handle
energy transfers to the wedge and
the gears, which opens the can.
Second is the wedge, the thing
that slices open the can is the
wedge. Third are the gears, those
little circles that grip and help
rotate the can are the gears.
Lastly is the lever, the arms of the
can opener are the levers. These
two levers open and close on one
fulcrum to grip and help open the
can. This can opener is located in
