Attach the rope to the hook on the ceiling, attach the magnet, attach a cannon ball, then swing it at the door. You need to do it three times. Good luck!

When a pendulum swings the size of the swing gradually reduces with time until the pendulum stops explain how this can be possible if energy is conserved?
Energy is conserved in an isolated system, meaning since energy cannot be created or destroyed, the amount of energy in the system is the same. The point is, what is the 'system' in a certain scenario. Even if the pendulum was in an isolated room, that doesn't mean the pendulum will swing forever, because energy is constsntly lost to the environment, due to the friction with the air. But while energy is lost from the pendulum, energy is gained by the surrounding air molecules (also isolated), and thus energy in the system is conserved. Eventually the pendulum's kinetic energy will be zero, having lost too much to be able to make it move.

No-one knows!Albert Einstein's last words were spoken in German. The only otherperson in the room was a nurse who didn't speak or understand German, soEinstein's "last words" remain a mystery.
Can a simple pendulum oscillate in a moving satellite?
A simple pendulum (a weight hanging from a string swinging back and forth) is a gravity driven system. The pendulum weight is released, falls down, swings through the low point, rises up until it reaches the same height as it was released on the other side, reverses direction and falls down. Satellites in orbit do not have an interior gravity field to drag things down (think of all the Shuttle photos with astronauts demonstrating floating pens and globs of water) so the description of the pendulum action would be: Pendulum weight is released and hangs there.The equation for the period of a simple pendulum:T=2 pi (L/g)0.5 (T=period, L=string length, g=acceleration of gravity)indicates the need for gravity field for the pendulum to swing. At zero gravity T goes to infinity. The pendulum does not swing.An Addendum:There was a followup question - what if the satellite was spinning (e.g. Had an artificial spin induced "gravity": So so far most of the shuttles and satellites with enough room to swing a pendulum have not enjoyed spin or other induced "artificial gravity" so I didn't consider it in the question. But it does sound like fun to think about. : I had started to develop a long explanation using the vectors of spin induced gravity in a spaceship. Then I had a flashback to a book I had back before satellites were in orbit. The picture was one of those old big wheel type habitats spinning in space. Workers just hung there in the axle area in their own orbit with no impact from the rotation (spin doesn't radiate gravity waves) This is not the case for the pendulum as it is attached to the spinning object and eventually moves in a way that causes it to become part of the rotation. This results from the weight's reaction on being released to move tangentially to the arc of the spin. : Since the spinning satellite is essentially a gyroscope it will orient itself (the axis of rotation)in one direction against space. The pendulum weight swing can have two components: in the same direction as this axis, and with and against the rotation. : In the case of the weight's component of swinging in the rotation plane, the weight is essentially always "down" as far as it can go. Like you spinning with a weight on a string, no matter how close you bring the hand holding the end of the string, the weight always pulls directly out i.e. no swinging : Regarding the component of swing back and forth along the axis, the force pulling on the weight (g) changes with the distance from the axis of rotation the "gravity" changes and the equation I presented for the pendulum in my answer becomes an integral of "g" In addition the weight, it moves antispinward as it falls. An odd image - a chain would hang straight down, a waterfall in a spinning satellite would curve to the antispinaward with every drop at 0 g as it "fell" : NOTE: A bit of experimentation in the back yard indicates that it is hard to get any up and down motion with a weight on a string when I'm spinning. It may be that this motion damps out pretty quickly. : So far we haven't considered pendulum being in the spinning satellite orbiting a planet. If the pendulum were just hanging there in a non-spinning orbiting object it would have a different orbital period from the center of mass of the satellite and a different orbital height for whatever speed it was released at. I think it's faster is lower and slower is further for orbits. We'd have to consider this as well in determining its motion if the pendulum swing took it effectively into a higher or lower orbit .

What are some metaphors in the story the pit and the pendulum?
The entire story is an extended metaphor for death and biblical judgement.The judges symbolize Death incarnate.When he is carried to the first room, it is like pall bearers carrying the dead to a funeral.While he is in the unlit room, prone, on a cold damp floor after being carried "in silence down--down--still down" into the ground, it is like being entombed but also like Purgatory.Poe even says "The pit, typical of hell" to let us know that is what it symbolizes.When he is tied down to the table below the pendulum, it is a symbol of the eternal torture of hell.The rats come to devour him as vermin would devour a body in a tomb.The walls closing in at the end glow and are painted with hideous images to remind him of hell.At the last second, when the trumpets blow and LaSalle reaches to save him, it is like God coming. The trumpets are an obvious symbol, as is LaSalle's (God's) hand reaching to save someone from eternal damnation.
