Newton’s Law of Motion is:

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

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

All listed here

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
