Let's say you wanted to use a pulley to lift a flag up a flagpole. If you wanted to lift the flag 10 meters in the air, how far would you have to move the rope?
5 meters
10 meters
15 meters
20 meters

a screw
an inclined plane
a lever
a wheel and axle
What is the effort force?
the force that you apply to a simple machine
the weight of the load that the simple machine moves
the distance that the simple machine moves the load
the amount of effort it takes to construct a simple machine
What is the force exerted by the load being lifted called?
the actual force
the resistance force
the effort force
the strong force
In a simple pulley, what is the relationship between the effort and resistance forces?
the effort force is smaller than resistance force
the effort force is larger than resistance force
the effort force outweighs the resistance force
they are equal
What objects can't you lift if you are using a single-pulley system?
very large objects
oddly-shaped objects
very tall objects
objects that are heavier than you
Let's say you had a pulley system with a mechanical advantage of 3. If you want to lift a boulder 10 meters off the ground, how far would you have to pull the rope?
3 meters
10 meters
30 meters
300 meters
It's easier to lift heavy objects with a double-pulley system because:
The effort force is twice as much as the resistance force.
The effort force is one-half as much as the resistance force.
The effort force is three times as much as the resistance force.
The resistance force and effort force are equal.
