Gravity Force

-magnitude decreases with distance


-magnitude increases with mass


-its effect accumulates


-dominant force on the scale larger than that of the Earth

Electromagnetic Force

-charged particles exert forces on other particles


-on a subatomic level they're much stronger than gravity


-above microscopic scale its neutral, therefore they are unimportant

Weak Nuclear Force

-much weaker than Electromagnetic


-governs the emission of radiation from radioactive atoms


-at high temperatures electromagnetic forces and weak nuclear forces combined to create electroweak forces

Strong Nuclear Forces

-the forces that blinds atomic nuclei and subatomic particles like protons and neutrons together


-strongest of all the forces but only at extremely small distances

Pair Production

-matter is created directly from energy


-two photons colliding can give rise to the particle-antiparticle pair


-they both annihilate each other producing radiation

Particle Equilibrium

-this exists when the number of particle creations exactly matches the number of annihilations


-they have no time to decay or combine before a collision happens
