Question
Use the image of the pulley to answer the question.
An illustration shows a system of two pulleys lifting a block.
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?

The force increases, while the distance decreases.
The force increases, while the distance decreases.
The force decreases, while the distance increases.
The force decreases, while the distance increases.
Both the force and the distance increase.
Both the force and the distance increase.
Both the force and the distance decrease.
1 answer
In a pulley system, the force required to lift a weight is usually reduced due to the mechanical advantage offered by the pulleys, while the distance through which the force is applied is increased.
So, for the question about how the values change when the pulley is applied:
The correct answer is: The force decreases, while the distance increases.
