The Laws of Physics in an Animation Universe


           If you’ve ever watched a Disney cartoon featuring Goofy, you know you’re in for some slapstick humor. The world of “A Goofy Movie” is very similar to the animated world of a classic Goofy cartoon. While the characters generally obey basic laws of gravity, there are also a lot of things that the film gets away with for the sake of humor. “A Goofy Movie” is about Goofy taking his teenage son Max on a cross-country fishing trip to bond with him because Goofy fears growing apart from his son. Thus begins this charming musical journey of a father and son reconnecting, but since it’s a movie starring Goofy, it can’t be too grounded in its physical realism.

               As all animation students know, the principle of “squash and stretch” is a very necessary tool to prevent an animated piece from looking too stiff but while retaining the volume of a character or object. In “A Goofy Movie” many objects are stretched beyond their physical capacities, and in many instances, what should have been a fatal accident is merely a humorous slapstick incident. At the beginning of the film, Max oversleeps and is woken to his dad barging into his room to vacuum. Goofy sees that Max’s room is a mess and starts to vacuum up everything on the floor—this includes large objects like clothing that could never fit through a vacuum nozzle. It all gets sucked up without an issue, which couldn’t happen in our world, but works for comedic effect in animation. Later in the film, when Goofy is pitching a tent he is interrupted by the arrival of his neighbor Pete’s huge trailer. The trailer sets up its many features as soon as it’s parked, which includes blades that shoot out to clear trees out of the area, a deck that swings out with everything (including drinks, chairs, and flower pots) all set up, an already filled hot tub which bursts out of the side, a basketball court, a rooftop bowling alley, and an entire pool which is also already filled. All of this is automatically set up in a matter of seconds. Not only could most of the objects not fit inside a trailer, but things like water would never stay contained in something like a hot tub or pool when “folded” back up and not in use. It would be amazing if a trailer like this could exist in our world, but it simply cannot. 


At the end of the film, when Max and Goofy return home, Max stops by his crush Roxanne’s house while Goofy works on some car repairs. While Max and Roxanne are talking on the porch, the car that Goofy is working on explodes, rocketing him into Roxanne’s roof. Goofy is perfectly fine and he and Roxanne shake hands in greeting. If this happened in our world, Goofy would never have survived that explosion or the impact into the roof (he also likely would not have arced into the roof in that manner)—it works for animated slapstick purposes. However, there is another moment near the end of the film where Goofy almost goes down a waterfall and he and Max react as though he is in real peril, which suggests that despite all of the slapstick humor and “low-stakes” stunts in the film, things such as terminal velocity still exist in this animated world.

               There are many cases in “A Goofy Movie” where characters defy gravity. Near the beginning of the film, Max tries to impress Roxanne by dressing as their pop idol Powerline and dancing to one of his hit songs. He swings from a rope at one point, arcing over the heads of the student assembly, doing twists and even dunking a basketball through a hoop. In our reality, his weight wouldn’t allow him to do so many stunts, swing that distance, or arc in such a way. 


During a montage later in the film, Max and Goofy attend a ballgame and when Goofy tries to catch a foul ball, he falls over the balcony, gets caught on a wire, and is dragged down to the dugout where he has time to get a player to sign the foul ball, before rocketing back up to Max safely. Were this to happen in real life, it would likely be fatal and Goofy certainly wouldn’t have enough time to have a baseball signed. Because this is a light-hearted montage, we believe that Goofy will be okay and survive these incidents, which is much different than the emotional high stakes near the end of the film. At one point in the movie, Goofy and Max get into a fight over map directions and while they’re out of the car arguing, their car starts to roll down the winding road around the Grand Canyon. This leads to many antics of the two characters trying to catch up to their car including opening doors as it moves, Max riding his skateboard under the car to get to the open door on the other side, the car itself running off the road onto an unfolding thin steel road barrier and then bouncing from rock to rock until it arcs into the river below with Max and Goofy on top of it. If this were to happen in our reality, Max and Goofy would never have caught up to their car and if they did, they would not have survived the journey down into the river below. Since the car followed the cartoony rules of “squash and stretch” it also wasn’t crushed on the rocks during its descent, and the animators changed how it fell into a more pleasing arc for the audience to watch. Realistically, this would have ended with the car smashing into one rock and then tumbling into the waters below, instead of bouncing from boulder to boulder before arcing from a boulder into the river. Despite these crazier moments of the film disobeying the laws of gravity and the correct weight of objects, there are moments in the film where weight does work correctly. For example, when Max and Goofy enter one of their motel rooms, they jump onto the water beds which could have been really over-exaggerated in the animation, but the way the beds shift underneath them is actually pretty believable.

               Finally, there is Goofy’s “perfect cast”, which is demonstrated a couple times during the film and deserves to be examined in its own section. Goofy first shows Max how to do the “perfect cast” at a lake while camping. Goofy does a lot of spinning in the air with the fishing line twirling around him—it does not tangle at all, which it would in real life. When Goofy finally arcs the pole backwards, the line flies all the way from the lakebed to Pete’s grill where it snags a steak. It is somehow able to be arced back in a similar fashion but with the heavy weight of the steak now attached to the line, which wouldn’t happen in our world. The line flies back over Goofy’s head all the way to the other side of the lake and lands with the steak still on the hook. The other performance of the “perfect cast” happens in the dramatic scene near the end of the film when Goofy is truly in peril. Max and Goofy were drifting in the river on their trashed car when the water starts rushing as they approached a waterfall. Goofy finds safety on a log by the river and snags the car with Max still on top of it with his fishing line. When this inevitably doesn’t hold, Max is saved by the fabric on the underside of the car becoming a makeshift parachute (which certainly wouldn’t hold his weight in a non-animated world). Goofy, trying to rescue Max, ends up back in the river and he goes over the falls. Max then has to make the “perfect cast” in order to save his falling dad. Not only does he have time to cast it (along with all the necessary spins) but the line doesn’t tangle, the line somehow reaches all the way down the falls to catch Goofy, the fishing line doesn’t break, and the makeshift parachute is able to hold both Max and Goofy’s weight. Needless to say, neither one of them could have survived this situation in real life and the “perfect cast” is more like the “impossible cast”, but in this animated world it made for a very emotional and tense scene.




               “A Goofy Movie” has many impossible moments in it, but it makes good use of its slap-stick animated world. It does not follow many laws of physics, especially when it comes to gravitational forces affecting certain weights and terminal velocity (except when it was a real threat during the dramatic climax of the film), but these laws are broken for a purpose. The creators intentionally broke them to add to the comedic value of the film and to support the “goofy” world that these characters exist in. I am incredibly charmed by this movie, and I was delighted to examine its improbable physics.
