The passage reference the torture of the pit and the pendulum, which involves a person being tied down with a pendulum swinging back and forth ready to slice them while they are also facing the threat of falling into a pit that will be their doom.
When a pendulum is hanging straight down, it has potential energy due to its position above the equilibrium point. This potential energy can be converted into kinetic energy as the pendulum swings back and forth.
No, at the top of a swing, the pendulum has potential energy due to its position above the ground, which is considered gravitational potential energy. There is no chemical energy involved in the motion of a pendulum at the top of its swing.
A pendulum has mechanical energy, which is made up of potential energy due to its height above the equilibrium position and kinetic energy due to its motion as it swings back and forth. This energy is constantly changing between potential and kinetic as the pendulum moves.
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
The height of an object above a reference point is the vertical distance between the object and the reference point. It is commonly measured in units such as meters or feet. The height is determined by subtracting the elevation of the reference point from the elevation of the object.
In "The Pit and the Pendulum," the narrator's madness is portrayed through his vivid and frantic descriptions of his surroundings, his paranoia and fear of impending doom, and his increasingly delusional thoughts and actions as he struggles to survive in the torture chamber. The use of sensory details and fragmented, repetitive narration further underscores his descent into madness.
The falling action of "The Pit and the Pendulum" involves the narrator falling unconscious and waking up to find himself strapped to a table as a pendulum swings above him, getting closer to cutting him. He then narrowly escapes death when the French army arrives to save him from the Inquisition's torture chambers.
The narrator initially fears that the Inquisition plans to torture him using a deadly pendulum swinging above him. He later discovers the truth when he narrowly escapes being sliced by the pendulum and is rescued by General Lasalle, who reveals that the Inquisition mistakenly forgot about him in the dungeon.
It doesn't change direction; there is no force on it (perpendicular to the plane in which it swings) that would cause it to do so. It APPEARS to change direction relative to the Earth, but the Earth is a rotating frame of reference. If you watch the pendulum from a frame of reference above the Earth and the pendulum, you would see that it swings back and forth in its plane of oscillation. See the famous movie FRAMES of REFERENCE, with Professors Hume and Ivey, made in 1959, to see an excellent demonstration of this. Using a rotating frame, they show that a camera in the rotating frame appears to show the pendulum changing direction. Using a camera above the rotating frame, fixed to the floor, they show the pendulum never changes direction; only the frame rotates. . It swings back and forth in the same plane. There is no force on it to make it change

We cannot help you - since we have NO way of seeing the 'above passage' !
Something above the point of reference in medical terms is called "superior."

We cannot read your mind and look at the "passage above" to see what it says, so there is no way to answer this question.

An Ellicott pendulum is a temperature compensated clock pendulum. The metal rod of a pendulum changes its length with temperature. The consequence is, that a colder pendulum swings faster (the rod is shorter) and a warm pendulum swings slower (longer rod). The Ellicott pendulum compensates this temperature error of the pendulum. It consists of a steele rod and two brass rods, wich are connectet in one point above the pendulum bob. Brass has a higher temperature coefficient than steele. On the free end of the three rods, a special lever mechanism, controlled by the lenght difference of the rods, lifts the pendulum bob up, when the length of the rods grows. The bob stays at its position and the period of the pendulum is without temperature influence. See also http://commons.wikimedia.org/wiki/File:Ellicott_pendulum.png
