Weight of a body

Which one isn't Newton's law

• every object continues in its state of rest or continues at constant velocity in a straight line unless a resultant force acts on it.

• the rate of change of momentum of a body is directly proportional to the resultant force acting on it, and the momentum change occurs in the direction of the force

• if body A exerts a force on body B, then body B exerts an equal force but in the opposite direction on body A.

• in a reaction force, it must me same magnitude and direction
