The Physical Law of Kinetic Energy for Feature Films
The physics laws of kinetic energy has been prevalent in visual presentations since the 20th century. These laws are constantly misused or broken to maintain the interest and action of the viewing audience. In my opinion, the three types of media that demonstrates the incorrect way kinetic energy is illustrated encompasses cartoons, live-action films, and graphic animation features. Cartoons are mainly designed for children and young adults from 5-25. The presentations contain outlandish events over a short period of time. In cartoons, kinetic energy involving speed are always shown and the audience doesn’t care whether or not physics laws are broken. People see cartoons as funny and the action that takes place as unreal. Live-action presentations are major films and the kinetic laws are designed to stress the imagination of the mind. Car chases, supersonic speed employed by individuals and objects, and armed conflicts between opponents are depicted in a dramatic and comedic way. Kinetic laws demonstrated in these films are usually fantasy that can be possible in the future but modern technology has not been develop at the present time to accomplish these ideas. The audience is not concerned with whether the scene of kinetic energy is fact or fiction but only as a way to heighten the excitement of the film. Graphic animation sometimes combines with live-action films and uses 3D and visual effects that usually are not employed by other media. It presents graphically produced individuals as real people and places them in situations where kinetic energy is used inaccurately to escape danger or enhance superheroes in a positive way. In many scenes, the images presented are continuously breaking the law of physics by animation techniques that defy reality and could not be done in modern society. This paper will describe the physics laws of kinetic energy in a cartoon, live-action film, and graphic animation feature and demonstrate why these visual presentations could not be adopted in real life.
The physics laws of kinetic energy are usually inaccurately illustrated in cartoons. In a scene from “Fur of Flying,” cartoon character Wile E. Coyote is depicted at a secret military base constructing a rocket that will help catch his prey the roadrunner. He finally completes his project, rolls it out to the desert, ties himself to the top of the rocket, starts and accelerate the projectile to supersonic speed, and begins to chase the roadrunner. During this pursuit, the roadrunner stops, while the rocket continues to pass him crashing into a mountain. The physics laws of kinetic energy are broken and cannot be applied for several reasons. First, a rocket slightly above the ground traveling horizontally at supersonic speeds would develop friction, which will create intensive heat and any living human being tied to the projectile would be burned beyond recognition. Second, the supersonic speed generated by kinetic energy would prevent Wile E. Coyote from remaining motionless in the center of the rocket, which would cause the projectile to veer off course and thus not capture the roadrunner. Finally, the wind force created by kinetic energy would blow into Wile E. Coyote’s body with such a velocity that it certainly will disintegrate him. Therefore, the scene that depicts Wile E. Coyote riding on a rocket breaks all the physics laws of kinetic energy, which makes it impossible to apply in real life.
“Back to the Future, Part II” is a film that incorrectly gives many examples about the physical law of kinetic energy and their possible use in time travel. In one scene, the time travelers are making final preparation for their journey into space. Dr. Emmett Brown (Christopher Lloyd) is packing some scientific equipment into the trunk of this futuristic car. Marty McFly (Michael J. Fox) and his girlfriend Jennifer are loading boxes of personal items necessary for the trip. The travelers then get into the car, back out of the driveway into the street, accelerate at supersonic speed, and disappear into the stratosphere on their way to their objective. The plan is to proceed towards their future destination of Oct 21, 2015 and return to earth with new discoveries that would beneficial to mankind. However, there are several factors encompassing the physics laws of kinetic energy that would make it impossible for this to happen at the present time. First, kinetic energy would have to accelerate the velocity to the speed of light or a 186,000 a second, which would increase heat and causing the vehicle to break apart or be destroyed in space. Second, should the vehicle and the occupants survive this ordeal, there is still the relativity factor. In physics, kinetic energy changes both relative speed and time. For example, if an automobile continues towards its destination, the travel time of the individuals is much slower while the people on earth would not experience any change at all. Thus, the time travelers would arrive on Oct 21, 2015 believing their time reference is the same on earth. When they return to earth, they would discover that thousands of years have elapsed and the world and people would have changed for better or worse. Therefore, kinetic speed, relativity, and time distortion are factors that would make it impossible for modern day travelers to embark on a space odyssey like the journey depicted in the film.
“The Incredibles” is a graphic animation film involving superheroes, who use the physics laws of kinetic energy to fight for truth and justice. During the film, kinetic energy enhances their special powers to destroy evil individuals, who want to rule the world. In one scene, superhero Dash is running through a forest pursued by villains that want to capture him. Eventually, he stops at a lake with his pursuers close behind him. Sensing danger, he employs his superpowers to run across the lake to escape his antagonists. However, while animators can create graphic characters to run across the lake, the physics law of kinetic energy cannot generate enough speed allowing human beings to perform the same task. The reason excessive speed is important is because every step taken by the runner must be done in a microsecond to distribute the weight, which will enable the surface tension of the water to support his body as he crosses the lake. Without supersonic speed, the weight of individual would cause him to sink into the water almost immediately. This is similar to a swimming pool covering that is supported by surface tension when spread out over the area but would sink to the bottom when rolled and thrown into the water due to the lack of weight distribution. Thus, kinetic energy depicting an animated character crossing a body of water could not be applied to individuals in a modern society.
Cartoons, live-action films, and graphic animations have inaccurately used the physics law of kinetic energy to provide the vitality and dynamics in each scene and maintain viewer interest of the storyline. For example, cartoons encompass kinetic energy in its characters that allows them to commit beatings, explosions, and other acts of violence on its adversaries in a comical way that will be acceptable by young audiences. Despite the aggressive acts, the characters are never killed or harmed that might detract from the comedic content of the story and the loyalty of cartoon fans. Live-action films use kinetic energy mostly to provide some understanding of a futuristic world and a plausible way the physics laws of nature that are not acceptable today may become a reality through new technology for the next generation. Graphic animation uses the physics laws of kinetic energy as part of its special effects and digital processing department to enhance the storyline that usually provides fictitious characters with magical powers and an unreal world that will never exist in real life. Thus, the physics laws of kinetic energy serves the purpose of film producers, who are more concerned with the profits of motion pictures then providing understanding and knowledge about the scientific principles that govern our world.
