Universal forces are fundamental interactions that govern the behavior of matter and energy in the universe. The four main types of universal forces are gravity, electromagnetic force, strong nuclear force, and weak nuclear force. Each of these forces plays a crucial role in shaping the structure and dynamics of everything from subatomic particles to galaxies. Gravity pulls objects toward one another, while the electromagnetic force affects charged particles, enabling electricity and magnetism. The strong nuclear force binds protons and neutrons in atomic nuclei, and the weak nuclear force is responsible for certain types of radioactive decay. Together, these forces create the framework for all physical interactions in the universe.
