Want this question answered?
A pulley is a force multiplier. (it swaps force for distance).
Do the moveable pulley decreases the input force?
simple machines like pulley, liver and fulcrum.
it helps to reduce effort
A simple machine. You know, inclined plane, lever, pulley, screw, wheel, or a wedge.

Do the moveable pulley decreases the input force?
fixed and movable pulleys can be combined.
It decreases the force.
To reduce the amount of force needed to carry objects into the truck k12
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
A pulley is a wheel with a groove on its edge for holding a rope or cable. pulleys are usally used in sets desinged to reduce the amount or force needed to lift a load.

Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
It would be more accurate to ask whuch pulley takes the least amount of FORCE. WORK=FORCE X DISTANCE so ultimately the amount of work will be the same depending on how far the load moves. If you are wondering which pully will be the easiest to use than you need to know something about pulleys. Each time a rope passes through a pulley, the amount of FORCE needed to move a load decreases. The more passes the greater the MECHANICAL ADVANTAGE. But, there is a trade off. You may not need to pull as hard, (less force) but you will have to pull more rope (greater distance) to move the load. So the total amount of work remains equal.
