The laws of physics are applied differently in cartoons. The Funny Pages has a list of 10 laws and 5 law amendments of cartoon physics, condensed here for your viewing pleasure. Check out the link though, for greater explanations.
Cartoon Law 1: Any body suspended in space will remain in space until made aware of its situation.
Cartoon Law 2: Any body in motion will tend to remain in motion until solid matter intervenes suddenly.
Cartoon Law 3: Any body passing through solid matter will leave a perforation conforming to its perimeter.
Cartoon Law 4: The time required for an object to fall twenty stories is greater than or equal to the time it takes for whoever knocked it off the ledge to spiral down twenty flights to attempt to capture it unbroken.
Cartoon Law 5: All principles of gravity are negated by fear.
Cartoon Law 6: As speed increases, objects can be in several places at once.
Cartoon Law 7: Certain bodies can pass through solid walls painted to resemble tunnel entrances; others cannot.
Cartoon Law 8: Any violent rearrangement of feline matter is impermanent.
Cartoon Law 9: Everything falls faster than an anvil.
Cartoon Law 10: For every vengeance there is an equal and opposite revengeance.
Cartoon Law Amendment A: A sharp object will always propel a character upward.
Cartoon Law Amendment B: The laws of object permanence are nullified for “cool” characters.
Cartoon Law Amendment C: Explosive weapons cannot cause fatal injuries.
Cartoon Law Amendment D: Gravity is transmitted by slow-moving waves of large wavelengths.
Cartoon Law Amendment E: Dynamite is spontaneously generated in “C-spaces” (spaces in which cartoon laws hold).
Which is your favourite cartoon law? Which would you like to be true in real life? Personally, I would like cartoon law 1 and 4 to be real. That would be brilliant!
