It's easier to pull downward than upward.

What kind of pulley changes the direction of input force but does not change amount of force you apply?
A single pulley alters the direction of the input but confers no mechanical advantage.
Do the moveable pulley decreases the input force?
Do the moveable pulley decreases the input force?
Which can change the direction of a downward input force into an upward output force?
A hanging pulley or a Class-I lever can both do that.
What is the input force and output force of a pulley?
The input force is how much force you use to pull on it. The output is what is lifted.
How does a fixed pulley affect the input force?

What kind of pulley changes the direction of the input force but does not change the amount of the force you apply?
They pulley is applied by the output force and then it is being added on by the input work.

The input force is how much force you use to pull on it. The output is what is lifted.
Unlike a fixed pulley a movable pulley multiplies the input force?
True
Does a fixed pulley multiply input force?
no it can't.

Does a moveable pulley multiply the input force?
Yes. The IMA of a movable pulley is 2.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
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.
Does a pulley system cause the direction of the output force to be opposite to the direction of the input force?
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.
How does a fixed pulley act as machine?
It changes the direction of the input force only
