Moveable Pulley – the pulley moves
on the string
Identify the pulley pictured above
and give an advantage of using this
type of pulley.
Figure 1
When using a moveable pulley, the
amount of force _____ and the
direction the load moves _____.
Figure 2 Figure 3
Figure 4
Which pulley system pictured above
would require the least amount of
force to lift the load? Explain
Figure 4 – the more pulleys you add,
the less amount of force needed
Force decreases
Direction the load moves stays the same
Fixed Pulley– the pulley is attached
to the ceiling
When using a fixed pulley, the
amount of force _____ and the
direction the load moves
_______.
What kind of pulley is pictured
above? How did you know?
It’s a fixed pulley and it changes
the direction that you lift the load
What kind of pulley is pictured
above? How did you know?
Force stays the same
Direction the load moves changes
