Question

A movable pulley reduces the amount of force needed to lift a load and makes what other change? OPTIONS The time that the load moves is reduced. The mass of the moving load is decreased. The direction the rope is pulled is reversed. The distance the rope is pulled is increased.

Answer 1

A pulley trades force for distance of rope traveled.

Essentially, someone is unable to lift a 100 pound object. However, they are able to move two 50 pound objects. It takes twice as long, and they moved the same amount.

Therefore, the answer is that distance the rope is pulled is increased
