A moveable pulley reduces the amount of input force needed to lift an object. By attaching the pulley to the object being lifted, the force needed to move the object is distributed between the pulling force and the weight of the object itself, making it easier to lift.
Do the moveable pulley decreases the input force?
The output force exerted by a moveable pulley when the input force is 50 N would be 50 N. Since a moveable pulley changes the direction of force but not its magnitude, the output force will be equal to the input force.
The output force exerted by a movable pulley is equal to the input force applied. Therefore, if the input force is 50 N, the output force exerted by the movable pulley will also be 50 N.
A single pulley alters the direction of the input but confers no 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.
Do the moveable pulley decreases the input force?
Yes. The IMA of a movable pulley is 2.
The output force exerted by a moveable pulley when the input force is 50 N would be 50 N. Since a moveable pulley changes the direction of force but not its magnitude, the output force will be equal to the input force.
The output force exerted by a movable pulley is equal to the input force applied. Therefore, if the input force is 50 N, the output force exerted by the movable pulley will also be 50 N.
They pulley is applied by the output force and then it is being added on by the input work.

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.
Depends what the input force is and the mechanical advantage of the pulley system If effort force (input force) is 20 pounds in a 6 pulley system (3 fixed,3 movable) then load force (output force) is 120 pounds As 6 times 20 equals 120 pounds
A pulley system may cause the direction of the output force to differ from that of the input force, but is not guaranteed to do so. In a simple example, a double pulley could easily result in input and output forces in parallel.
The input force is the force applied to the pulley by the person or machine. The output force is the force exerted by the pulley to move the load. The output force is typically higher than the input force due to mechanical advantage.
A fixed pulley changes the direction of the input force without changing the amount of force applied. It is attached to a fixed point and does not move, simply redirecting the force in a different direction.
A simple machine like a pulley can multiply and change the direction of an input force. By using multiple pulleys in a system, you can create a mechanical advantage that amplifies the force applied.
