What is considered the weakest of the four fundamental forces?

The weakest of the four fundamental forces in the universe is gravity. Despite being easily observable and having significant effects on large scales, such as the motion of planets and galaxies, gravity is fundamentally much weaker than the other forces.

For example, even a small magnet can easily overcome the force of gravity that acts on a paperclip. In the realm of fundamental forces, the electromagnetic force is stronger, influencing charged particles and governing chemical reactions. The strong nuclear force plays a crucial role in holding the nuclei of atoms together, overpowering the electromagnetic repulsion between positively charged protons. The weak nuclear force, although stronger than gravity, primarily affects subatomic particles during processes like beta decay.

Thus, gravity's relative weakness becomes evident in comparison to these other forces, making it the least strong among them.
