  • newtons third law
    if body A exerts a force on body B, body B will exert an equal and opposite force on body A
  • newtons second law
    force is equal to the rate of change of momentum
  • elastic collision

    kinetic energy before colliding is equal to the kinetic energy after
  • inelastic collision
    kinetic energy before the collision is not equal to the kinetic energy after after a collision
  • conservation of momentum
    the vector sum of the momenta of bodies in a system stays constant even if forces act between the bodies, provided there is no external resultant force
