The first law says that an object at rest tends to stay at rest, and an object in motion tends to stay in motion (with the same direction and speed) unless acted upon by an unbalanced force.. RD.

If the external force on an object is not zero, the objet accelerates in the direction of the net fore. The magnitude of the acceleration is directly proportional to the net force and inversely proportional to the objects mass. . Newton’s method. Need initial guess and derivative.
