Real-World Examples of the Strong Nuclear Force in Action

⚛️ Quick Study Guide

• 🍎 The strong nuclear force is one of the four fundamental forces in nature, the others being gravity, the weak nuclear force, and electromagnetism.
• 💪 It is the strongest of all forces, about $10^{38}$ times stronger than gravity.
• 🔒 The strong force holds quarks together to form hadrons, such as protons and neutrons.
• ☢️ It also holds protons and neutrons together in the atomic nucleus.
• ➡️ The force is mediated by gluons, which are massless particles that carry the strong force.
• 📏 The strong force has a very short range, typically on the order of $10^{-15}$ meters (1 femtometer).
• 💥 Nuclear reactions, such as nuclear fission and nuclear fusion, are manifestations of the strong nuclear force.
