The weak nuclear force is one of the four fundamental forces in nature that governs interactions between subatomic particles. It is responsible for certain types of radioactive decay and plays a role in the fusion reactions happening inside stars.
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.
The strong nuclear force binds protons and neutrons together within an atomic nucleus.
