    The Four Fundamental Forces Why does Earth stay in orbit around the Sun? How does light travel? What holds atoms and nuclei together? For centuries, scientists have sought to describe the forces that dictate interactions on the largest and smallest scales, from planets to particles.

  6. A fundamental force of nature is an attraction or repulsion between objects as described through interactions between fields and particles. Physics has identified four basic types of these interactions, which together describe every action we see...

  7. Jun 13, 2024 · Fundamental force, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces.
