The strong nuclear force is one of the four fundamental forces in nature that holds atomic nuclei together. It overcomes the repulsive electromagnetic forces between positively charged protons, allowing stable atoms to exist.
While the strong nuclear force holds atomic nuclei together, the weak nuclear force governs certain types of radioactive decay.
This force is responsible for interactions between charged particles, such as electrons and protons.
The gravitational force is what keeps objects attracted to each other due to their mass.
