A movable pulley changes the direction of the force applied to move an object. It allows the user to pull downwards or sideways instead of having to lift the object straight up. This type of pulley also reduces the amount of force needed to lift the object.
The two kinds of pulleys are fixed pulleys and movable pulleys. Fixed pulleys are stationary and change the direction of the force applied, while movable pulleys have a free end that moves and both change the direction of the force and provide a mechanical advantage.
A movable pulley can change the direction of the input force. When a force is applied downwards on one end of the rope, it causes the pulley to move upwards, lifting the load attached to the other end of the rope.
Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
A movable pulley reduces the amount of force needed to lift an object because it changes the direction of the force. When using a movable pulley, the load is shared between the pulley and the user, making it easier to lift heavy objects.

Yes an elevator is a movable pulley!

single fixed pulley, single movable pulley and single fixed and movable pulley. :-)

a pulley that is attached to the resistance and moves with it
multiply
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
