What are the fundamental forces - strong, weak, electromagnetic, and gravity Strong nuclear force - -a powerful force of attraction that acts only on the neutrons and protons in the nucleus, holding them together -electric repulsion of p+ strains nucleus but the (residual) force holds the nucleus together. -binds quarks and gluons and anti-quarks together into combinations that similarly have cancelling effects. Electromagnetic force - -survives to larger distances, but though not very strong is still strong enough to bind up most electrons and atomic nuclei into electrically-neutral combinations, whose electric forces on other objects cancel. -a force associated with charged particles, which has two aspects, electric force and magnetic force -the attractive or repulsive force between electric charges and magnets Weak nuclear force - -act within a nucleus to hold it together; involved in radioactivity; acts over a shorter distance -force between neutron and e-, p+, or antineutreno -The weak interaction is responsible for radioactive decay, which plays an essential role in nuclear fission (the rxn that powers the sun & thermonuclear (hydrogen) bombs) becomes extremely weak at long distances just like Higgs force
