The force decreases, while the distance increases.

The force increases, while the distance decreases.

Answer 1

When a pulley is applied to lift a weight, the force required to lift the weight typically decreases because the pulley can change the direction of the force and distribute the weight effectively. However, the distance through which you must pull the rope usually increases.

In this scenario, with a pulley:

• The required force to lift the weight decreases.
• The distance over which you must pull the rope increases.

So the correct response is:

The force decreases, while the distance increases.
