How does a pulley make work easier when it is used to lift an object?(1 point) Responses It increases the amount of work produced to lift the object. It increases the amount of work produced to lift the object. It reduces the weight of the object being lifted. It reduces the weight of the object being lifted. It changes the direction of the lifting force to work with gravity. It changes the direction of the lifting force to work with gravity. It decreases the distance over which the force must be applied to lift the object.

The correct response is: It changes the direction of the lifting force to work with gravity.
A pulley allows you to lift an object by pulling down, which can be easier than lifting the object straight up. While it does not reduce the weight of the object or decrease the amount of work done, it does make the lifting process more manageable by changing the direction of the force applied.
