  1. 3 forces acting on a body F1F2F3 on mass m and F1 is reversed in direc. then a=
    -2f1/m
  2. with surface;mv=
    2mvsin*
  3. normal to surface ;mv=
    2mvcos*
  4. change in the movementum when the ball bounces (daily)
    m(v+u)
  5. in circle change in movementum
    2mvsin*/2
  6. general formulae for force
    m dv/dt+v dm/dt
  7. inertial mass of the body
    F/a
  8. apparent weight of a body in lift when it is moveing up
    w=m(g+a)
  9. apparent weight of a body in lift when it is moveing down
    w=m(g-a)
  10. inside a train,effective a is
    root g2+a2
