# Newton’s second law of motion?

Relevance

The net force on an object is equal to the addition of all the outside forces acting on it

The acceleration of an object is directly proportional to the net force.

The acceleration of an object is inversely proportional to the mass

Weight is equaled to mass multiplied by the acceleration due to gravity.

The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. — If a force generates a motion, a double force will generate double the motion, a triple force triple the motion, whether that force be impressed altogether and at once, or gradually and successively. And this motion (being always directed the same way with the generating force), if the body moved before, is added to or subtracted from the former motion, according as they directly conspire with or are directly contrary to each other; or obliquely joined, when they are oblique, so as to produce a new motion compounded from the determination of both.

Newton's 2nd law: The rate of change of momentum of a body is proportional to the resultant force acting on the body and is in the same direction.

Second Law

The rate of change of momentum of a body is directly proportional to the impressed force and takes place in the direction in which the force acts.

Definetely Newton's First Law of Motion. When engines off, the spacecraft experiences no force. So, there is no acceleration. And hence, it will continue to move on with a specific constant velocity in a particular direction forever until disturbed by any unbalanced force.

The rate of change of momentum of a body is directly proportional to the impressed force and takes place in the direction in which the force acts. There u go!!!

hope it helps
