- Gravity. Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides.
- The weak force. The weak force, also called the weak nuclear interaction, is responsible for particle decay. This is the literal change of one type of subatomic particle into another.
- Electromagnetic force. The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons.
- The strong nuclear force. The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature.

- 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.
- Gravitational Force. The most familiar force is gravity. It is responsible for keeping our feet on the ground and holding Earth in its orbit around the Sun.
- Electromagnetic Force. Our television sets are powered by electromagnetism. Light carries this force, which illuminates our houses at night, keeps electrons in orbit around atomic nuclei, and allows chemical compounds to form.
- Strong Nuclear Force. Nuclear forces affect our daily lives, but they work on distances smaller than atoms. The strong nuclear force, or strong force for short, holds together the building blocks of atoms.
Learn how physics describes the attraction or repulsion between objects as interactions between fields and particles. Discover the strong nuclear force, electromagnetism, the weak nuclear force and gravity, and their effects on the Universe.
Jun 13, 2024 · Learn about the four basic forces of nature: gravitational, electromagnetic, strong, and weak. Explore how they act on different particles, their relative strengths, ranges, and mediators.
