What is a Strong Force? Strong force is one of the four fundamental forces of the universe. Other forces are gravitational force, weak force, and electromagnetic force. Also, as the name suggests, it is the strongest of all four forces, 100 times stronger than electromagnetic force, million times stronger than weak nuclear force, and 100 trillion trillion trillion times stronger than gravity. The strong force acts at a very, very small distance only, it has a very short range. The strong force is responsible for keeping the nucleons (protons and neutrons) together inside the nucleus of an atom. Credit: Science facts The strong force is responsible for The strong force is responsible for holding proton-proton and proton-neutron together in the nucleus. The nucleus is a dense region of the atom around which the electrons form an electron cloud. Since protons are positively charged, they repel each other. But this repulsion is neutralized, and protons are held together with this strong f
