In particle physics, a hadron is a composite subatomic particle made of two or more quarks held together by the strong interaction. They are analogous to molecules that are held together by the electric force. Most of the mass of ordinary matter comes from two hadrons: the proton and the neutron, while most of the mass of the protons and neutrons is in turn due to the binding energy of t… green and yellow flag with blue circleWebbThe strong force, electromagnetic force, weak force, and gravitational force are the four forces. it can be observed that Hadrons are the heaviest particles, whereas leptons are the lightest.
