General physics

The triangles provide a learning aid. They are not an alternative way of writing the formula.
  • period of pendulum =  total time 

     number of swings 
    T =  t 

  • distance= speed × time
    d= vt
  • acceleration=  final velocity − initial velocity 

    a=  v − u 

    =  v 

     if u is 0
  • weight = mass × gravitational field strength
    W= mg
  • density=  mass 

    ρ=  m 

  • force= mass × acceleration
    F= ma
  • force= spring constant × extension
    F= kx
