A "Force Field" is a concept often used in physics and science fiction to describe a barrier that can repel or contain objects or energy. In physics, it refers to the area around an object where a force, such as gravity or magnetism, can be felt. For example, the gravitational force field around the Earth keeps satellites in orbit. In science fiction, a force field is typically depicted as an invisible shield that protects against attacks or environmental hazards. These fictional force fields are often seen in movies and books, such as those featuring Star Wars or Star Trek, where they provide defense against weapons or space debris.
