For my physics 20 class, we were assigned to find a video, preferably action, that displayed some law breaking or proving physics.
Me being the geek that I am, I chose, Advent Children. Cause that movie totally follows the rules of physics, right?
Turns out it actually does, here's my work I handed in, thought you guys may be interested to find out the characters in AC aren't super human, their planet is just really small:
Physics 20 Video Project
Chosen Movie: Final Fantasy VII: Advent Children
Chosen Scenes:
Scene 1: Chapter 20, Shows two characters jumping from building in chase after an object. After free falling for roughly 38.5 seconds, the character catches the object and lands, (uninjured from the 12 story fall), hops onto his motorbike, and drives away.
This scene has been picked to not prove/disprove any physics, but to actually calculate the acceleration of gravity on this world, since it is painfully obvious that it is most definitely not -9.81. Characters seem to float down through the air with borderline buoyancy.
D= 12 stories x 8 feet = 96 feet = 29.2608 meters
Vi = 0.0 m/s
T = 38.5 s
Acc = ?
Calculations:
D= ViT+1/2AT^2
D= 1/2AT^2
2D = AT^2
(2D)/9T^2)= A
A = 2(29.2609m)/(38.5s^2)
Answer: -0.039 G (Calculated for 2 other scenes and actually added up. So it appears the acceleration of this planet the characters are on is close to the acceleration of the moon)
Scene 2: Chapter 8, Battle Beteen Tifa / Yazoo
Now that we have found the acceleration of gravity, we can explain how halfway through the scene, Tifa (the female character) is launched at a wall, and she is somehow able to “land” on the wall, look up, and then jump back off of it. The total time she is on the wall is .75 seconds, since most of the portion she is portrayed looking up, it is in quarter time. Thus, for every second on screen, it is actually .25 of a second in real time.
Now, we’ll calculate how far she would’ve fallen, Vi starting at 0, and falling for .75 seconds at this slow acceleration due to gravity.
Vi = 0
Acc = -0.039
D= ?
D=Vit+1/2AT^2
D=1/2AT^2
D=1/2(-0.039)(0.75^2)
Answer: 0.01 Meters.
Thus, she only slid down a total of 1 centimeter. If the wall was frictionless. Add in friction, and suddenly it seems very possible to have jumped off the wall in this borderline gravity less world.
Sorry if the work seems funny, it's hard to put in math equations on internets forums.
