How does a pulley make work easier?

• By reducing friction between surfaces

• By changing the direction of a force

• By allowing you to spread a weaker force out along a longer path

• By converting a small force over a long distance into a larger force over a shorter distance

What is a screw?

• A machine that uses a wheel with a rope wrapped around it

• A flat surface with one end higher than the other

• Two inclined planes placed back to back

• An inclined plane wrapped around a pole

How can simple machines be combined to form complex machines?
