Question

Lifting the weight without a pulley requires a force of 400 newtons over a distance of 4 meters. How do these values change when the pulley is applied? (1 point) Responses Both the force and the distance decrease. Both the force and the distance decrease. Both the force and the distance increase. Both the force and the distance increase. The force increases, while the distance decreases. The force increases, while the distance decreases. The force decreases, while the distance increases.

Answer 1

When a pulley is applied to lift a weight, the system typically reduces the amount of force needed to lift the weight while increasing the distance over which the force is applied. This is because the pulley provides a mechanical advantage.

In the case presented, the weight requires a force of 400 newtons without the pulley. When a pulley is used, the force required to lift the same weight typically decreases (depending on how the pulley is configured), while the distance over which you pull the rope or cable increases.

Therefore, the correct response is: **The force decreases, while the distance increases.**
