Forces and motion equations

Notes

Forces and motion

  • average speed =  distance moved 
     time taken 
    v =  s 
     t 
     
  • acceleration =  change in velocity 
     time taken 
    a =  (v - u) 
     t 
     
  • force = mass × acceleration
    F= m × a
     
  • weight = mass × gravitational field strength
    W= m × g
     
  • momentum = mass × velocity
    p= m × v
     
  • moment= force × perpendicular distance from the pivot
    M= F × d
