A wheel is an example of pulley
Potential energy is the energy that can be released, but has not been released yet. Ex. Sitting at the top of a slide is potential energy. You will eventually have to go down. Kinetic energy is the energy that is being released at any moment. Ex. As you slide down the slide kinetic energy is released.
A pulley does not save energy; it merely changes the direction of the force.
When the pully is not active, it is using potential energy. But when a person or a machine uses the pully, they use force to make Kinetic Energy and to lift the box....but that's what i know so far...but i . :)

because the gravitational energy of the load is absorbed by the pulley, so all effort is put into lifting the object as opposed to keeping it in the air

An example of a fixed pulley would be a well. This is a fixed pulley because the pulley doesn't move even though it is attached to an object.
A pulley on its own does not require any energy, as it's not doing anything.
When the example of pendulum is considered, from the topic of simple harmonic motion (SHM) potential and kinetic energy becomes very important. Kinetic energy is the energy of an object due to its flow and potential energy is the energy of an object due to its height.At various points in swinging pendulum following relation ship is used:mgh = 1/2mv2Where m= mass, h = height, g = gravitational constant and , v = velocity.
No it is not. A belt, for example, goes around a pulley.
yes
