What is Force or Interaction ?
Looking at an Electron in Detail
We find it juggling photons!
When another electron nearby the first takes a juggled photon away, the momenta of the two electrons change by the amount that the exchanged photon had.
Vertices that Govern Fundamental Forces
g: large interaction: strong
Apparent strength of a force and the mass (M) of the corresponding force carrying particle
- M: small -> force particles fly long distance
- M=0 -> force particles fly infinite distance (long-distance force)
- M: large -> force particles fall short (short-distance force)
