Simple and Complex
Machines
Simple Machines- the ability to do work
Complex Machines- two or more simple
machines that work together to do work

There are 6 simple machines:
• Inclined Plane- ramp or
slanting surface that
connects a lower level to
a higher level
• Lever- stiff bar that rest
on a support called a
fulcrum
• Pulley- grooved wheel
with a rope or cable
around it
• Screw- an inclined plane
wrapped around a pole
• Wedge- slanting side
ending in a sharp point
used to split, lift, or hold
• Wheel and Axle- circular device with a rod,
called an axle, through its
center

Inclined Plane- allows things to
move up or down it

Screw- holds or lifts things together
