Gravity is the weakest of the four fundamental forces, significantly weaker than electromagnetism and the nuclear forces. Electromagnetism, as its name suggests, operates on particles possessing electric charge, governing phenomena like electricity and magnetism. The weak nuclear force is responsible for certain types of radioactive decay, specifically beta decay, where a neutron can transform into a proton or vice versa. The strong nuclear force is the most powerful force over very short distances, overcoming the electromagnetic repulsion between protons to bind protons and neutrons together within the atomic nucleus.
