What are the relative strengths of the four fundamental forces?

Since gravity has very little effect at the atomic level, it is frequently regarded as the weakest force. Despite this, gravity has a very long range; it is responsible for the formation of stars, planets, and galaxies as well as the motions of bodies within solar systems and stars within galaxies.

Since Einstein demonstrated that acceleration and gravity are equivalent, we can use Newton's laws to describe gravity as a force as long as the objects are not too massive or moving at too fast speeds. In reality, gravity is actually the curvature of spacetime.

Radioactive beta decay is caused by the weak nuclear force, which is limited to the atomic nucleon scale. Because of its slow acting nature, radioactive nuclei can take a very long time to decay. A typical weak interaction is the decay of a neutron into a proton and a W boson, which in turn decays into an electron and an electron anti-neutrino.

The way that electrons and an atomic nucleus form atoms and how electrons interact in chemical reactions are both governed by the electromagnetic force, which also describes electricity and magnetism and governs the interaction between charged particles.

Protons and neutrons are bound into atomic nuclei by the strong nuclear force, which is thought to be the strongest because it overcomes the electromagnetic force's effect, which makes positively charged protons repel one another. In reality, the strong nuclear force is actually a residual effect of the color force, which is what binds quarks into nucleons.

The electromagnetic force, the weak nuclear force, gravity, and the strong nuclear force are the four fundamental forces, ranked from strongest to weakest.
