|
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 |
