Which fundamental forces are discussed in classical physics?

In classical physics, the primary focus is on the four fundamental forces that govern interactions in the universe. These forces include:

1. Gravitational Force: This force is responsible for the attraction between two masses. It's one of the most familiar forces, as it governs the motion of planets, the fall of objects to the ground, and tides.

2. Electromagnetic Force: This force acts between electrically charged particles. It encompasses both electric forces (like static electricity) and magnetic forces (like those found in magnets), and it plays a critical role in chemical reactions, the behavior of atoms, and even the structure of matter.

3. Strong Nuclear Force: This force binds protons and neutrons together in atomic nuclei. While primarily regarded in the realm of nuclear physics, it can be conceptualized in classical terms when discussing the stability of atomic structures.

4. Weak Nuclear Force: This force is responsible for certain types of radioactive decay and interactions involving neutrinos. Although it is more commonly associated with particle physics, it is still a fundamental force recognized in the broader context of physics.

The inclusion of all four forces—gravitational, electromagnetic, strong, and weak—in classical physics illustrates a comprehensive understanding of the interactions that occur in nature, even
