It holds protons and neutrons together to form atomic nuclei. Within its range, it is stronger than gravity, but not quite as strong as electromagnetism. It governs the creation and interaction of the elementary particles known as neutrinos. These are created when neutrons become protons or protons become neutrons. Neutrinos interact weakly with atomic matter because it is necessary for them almost to touch the nucleus before the weak force can cause them to interact.
Lightning occurs when the ground and the clouds are at different electrical potentials.
All particles of matter are mutually attracted due to their mass, resulting in the fundamental force called gravity. The weakest of the forces, it controls the movement of planets, stars and galaxies, as well as holding objects on the Earth's surface. The weak nuclear force is stronger than gravity but weaker than either the strong nuclear force or electromagnetism. Some methods of radioactive dating rely on this decay process. Everytime such a reaction takes place, a neutrino is released or absorbed.
