Newton’s Law of Motion is:

All listed here

To every action, there is always an equal and opposite reaction

Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force

The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts
