Momentum and Newton's laws of motion — practice question

Which option is not a statement of one of Newton’s laws of motion?

  • AIf body $X$ exerts a force on body $Y$, body $Y$ exerts an equal and opposite force on body $X$.
  • BIf no resultant force acts on a body it has constant velocity.
  • CThe rate of change of momentum of a body is proportional to the resultant force acting on it and takes place in the direction of the force.
  • DThe total momentum of a system of interacting bodies is constant if there is no external force.
