17. How are moving pulleys different from fixed-position pulleys? (Points : 3) Moving pulleys have more force than fixed-position pulleys. Moving pulleys are easier to use than fixed-position pulleys. Moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move. Moving pulleys are attached to the object and are stationary. Fixed-position pulleys are connected to a fixed point and move freely.

Which pulley setup would decrease the amount of effort force needed to lift an object?       (Points : 3)
       one moving pulley attached to the object that is being lifted

       one fixed-position pulley attached to a fixed point above the object that is being lifted

       two fixed-position pulleys attached to a fixed point above the object that is being lifted

       no pulleys, just a string attached to the object that is being lifted
