Physics in Cartoons

The cartoon that was analyzed by our group was the Disney movie The Emperor's New Groove. This movie is very entertaining and comical, however when a closer look is taken at the use (or lack thereof) of Physics Laws, many errors can be found. The following are four examples of situations in The Emperors New Groove where the laws of physics were over looked and ignored in the creation of the scene.

#1 (19:05-19:48)

After Emperor Kusko is turned into a lama, he is put into a cloth bag and thrown into a stream. The bag travels with the current until it falls over a waterfall. Since the bag is cloth and would therefore, absorb and fill with water, the lama and the bag

He stands roughly a foot in front of the pond and looks in to see his reflection is no longer that of a human. Since the water is acting as a plane mirror, <i = <r, with reference to the normal (perpendicular to the surface. In this case vertical.) Because of this law, the above is impossible. If the lama were looking at the water at a certain angle, the image could only be seen by somebody at that same angle on the other side of the normal. For the lama to see his own image, he would have to look straight down at the water so that he is looking along the normal. The following would be true <i = <r; 0 = 0.

#3 (28:34)

In this scene, Kusko finds himself in the middle of a group of sleeping panthers. An upset chipmunk (who is several feet away from Kusko) blows up a balloon and pops it hoping to wake up the panthers that will then eat Kusko. When the chipmunk pops the balloon, it creates so much of a draft that it almost blows the lama away. This is inaccurate because the air that would be expelled from the balloon is only as much air that was contained in the balloon to begin with. The pressure in the balloon is higher than the pressure outside the balloon. Since air follows the concentration gradient, (high to low pressure) when a hole is put in the balloon, the high-pressure air inside follows the gradient and rushes
