| Mass (specifically {{w|rest mass}}) is the measure of an object or particle's resistance to force, as well as its ability to distort {{w|spacetime}} (its gravitational attraction). | | Mass (specifically {{w|rest mass}}) is the measure of an object or particle's resistance to force, as well as its ability to distort {{w|spacetime}} (its gravitational attraction). | ||

The mass units shown (kilograms) are, however, far too large for particles. Some particles, such as photons, have zero rest mass and are therefore massless. |
All particles with rest mass obtain it through confinement, either by the {{w|Higgs field}} (the quarks; leptons; and W, Z, and Higgs bosons) or the strong nuclear force (hadrons). | All particles with rest mass obtain it through confinement, either by the {{w|Higgs field}} (the quarks; leptons; and W, Z, and Higgs bosons) or the strong nuclear force (hadrons). |
