1

Air resistance (proportional model)

R = -bv

vT = mg/b

v = vT(1-e(-t/T))

  • T=m/b

2

Air resistance (squared model)

R= (DρAv2)/2

vT = sqrt(2mg/DρA)

3

centripetal acceleration

ac = v2/r

4

fundamental forces

  • gravity

  • electromagnetism

  • strong force

  • weak force (beta decay)
