Formulae

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 

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

     time 
    a=  v − u 

     t 
    =  v 

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

     volume 
    ρ=  m 

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