Physics and RoTK??!

We're discussing the movies, and so I think that you meant to write nuts...

Regarding the Black Gate, was the bar perhaps made of mithril?

[Beanamir of Gondor]

I've got one! How about Grond the battering ram used during the Siege of Gondor? Calculating the weight, angle, and velocity needed to break the Gate of Minas Tirith must have been a pain for those silly trolls.
How about the perfect angle at which to attach the stirrup to David Wenham's leg as not to break his ankle when Faramir was being dragged in though the Gates... in full armour... stuck full of arrows... *trails off into grumbling*

The trebuchet one was great, Sir Kohran.

Not sure. In one telling of the story the Gates of the Morannon are made by the Men of the West, and I don't think that they would have invested precious mithril into this gate. The Gate for Minas Tirith contained mithril, but from my reading it was more decoration than function. After King Elessar becomes King, the Gate is newly wrought with mithril (I'd use it in the hinges ).

Anyway, in PJ's Black Gate, we have a troll team used to open it. Would Sauron, who coveted mithril, used this precious metal for something so base as a door handle?

[Knight of Gondor]

Scenes from Return of the King in which physics might be discussed:

• Gollum hanging down towards the beginning
  
• The arrow fired by Legolas to pierce Wormtongue
  
• Saruman's plunge
  
• The distance of the Palantir and how far it rolled
  
• Sam's fall down the stairs after leaving Frodo, perhaps including the fall of the Lembas crumbs
  
• Siege towers for the assault against Gondor
  
• The Witchking's mace; wielding it, dislodging it from the ground, etc.
  
• Grond and other siege weapons
  
• The return-fire from Gondor (using sections of their own wall)
  
• The difference of siege weapons between the lever action of Mordor and the sling-type action of Gondor
  
• The Nazgul terrorizing the people and weapons on the tops of Gondor...the distance it took for the Gondorian victims to fall before hitting the roofs below
  
• Bracing the door (brace versus the force from the other side, being banged on by the troll with the hammer) when Gandalf and Pippin are waiting for the breech of the second (third/fourth?) tier gate, when they discuss the white shores
  
• Denethor's flaming plunge
  
• How Aragorn, Legolas and Gimli would likely have sustained injuries from their jump off the ship if they'd made it in real life
  
• Legolas versus the Oliphants...sliding off the trunk and landing unharmed right in front of Gimli
  
• Aragorn dropping the Evenstar pendant, and its subsequent shattering
  
• Gollum's fall
  
• The fall of one of the Dark Riders when his mount is attacked by an eagle
  
• The destruction of the Dark Tower (Golly, I hope you've already seen the film! )

Covered enough topics? I'm guessing if you want to narrow in, the siege weapons would be a good thing to go with. It's a topic of physics that still affects battle strategy today, and has several facets of interest in the movie.

I've just finished my paper.. and took a lot of ideas from here. I quoted this site of course, to avoid the university plagiarism thingy....
