What are the conservation laws.

  • conservation of charge

  • conservation of baryon number

  • conservation of lepton number.

2
New cards

What are the four fundamental forces of the universe?

  • gravitational

  • weak

  • strong

  • electromagnetic

3
New cards

Gravitational force

  • all matter

  • infinite range

  • is the weakest of the fources.

4
New cards

Weak

  • leptons, and quarks

  • short range

  • change in quark flavour

  • 10^-10 lifetime

  • if neutrinos are present it is weak.

5
New cards

strong

  • 10^-24 lifetime

  • all particles are hadrons

  • leptons dont feel it

  • no change in quark flavour

6
New cards

electromagnetic

  • short lifetime 10^-12 10^-18

  • if gamma photon emitted it is em

  • charged particles only

  • no change in quark flavour
