How does a pulley make work easier?

• By increasing the weight to be lifted

• By reducing the mechanical advantage

• By making the work more difficult

• By distributing the weight over multiple ropes and pulleys

What is an example of a wheel and axle?

How does a lever help to lift heavy objects?

• By using a pivot point to apply a larger force over a longer distance to lift a lighter load over a shorter distance.

• By using a pivot point, or fulcrum, to apply a smaller force over a longer distance to lift a heavier load over a shorter distance.

• By using a lever to apply the same force over the same distance to lift a heavier load over a longer distance.

• By using a lever to apply a smaller force over a shorter distance to lift a lighter load over a longer distance.
