Before going any further, best that I announce my candidacy for the world sort out of the physics of Sir Isaac Newton. Feel free to vote for the status quo if you wish.
Newton's first law "Every body perseveres in its state of being at rest or of moving uniformly straight forward except insofar as it is compelled to change its state by forces impressed
Sir Isaac Newton's first law of motion is not a unique law of motion. It is two laws of motion joined together.
The first of the two laws that Sir Isaac employed is an object will remain at rest or in uniform motion in a straight line. This part is the conservation of the momentum of a free travelling body. In physics school books the momentum of a free travelling body is defined as the product of the mass of the body multiplied by its velocity.
Momentum does have a school book law that is to do with its conservation. That law states that when two bodies collide the momentum present before the collision equals the momentum present after the collision. The classic or simple example is a pair of billiard balls in action. The moving ball has original momentum. When it collides with the other ball, the first ball loses some momentum and the one that was stationary gains some momentum. Afterwards the sum of the horizontal momentum of the two balls is equal to the horizontal momentum of the ball that was moving first.
That is basis of the law of the conservation of momentum that we have in the schoolbooks. That law only holds true if the momentum of the isolated moving billiard ball is conserved prior to the collision. Mathematically we can understand how this is so. Two numbers multiplied together yield one answer. When one of a pair of multiplied numbers represents the mass of the body and another number represents the velocity of the body there is always only one answer. And that mathematical fact is the precursor to the conservation of momentum after two bodies collide.
Thus the first part of Sir Isaac Newton’s first law, an object will remain at rest or in uniform motion in a straight line, is simply the conservation of the momentum of an isolated free travelling body.
The second part of Sir Isaac’s first law is the introduction of a collision of some type. Then an isolated free travelling body is subject to an external force and at face value, that is the end of Sir Isaac Newton's first law of motion. All it says is momentum is uniform unless an outside force disturbs uniform momentum.
Not really relevant to Sir Isaac's first law as it stated in the schoolbooks but the acceleration or deceleration of the body subject to an external force is explained by Sir Isaac Newton’s second law. That law states that the acceleration of a body is directly proportional to the force applied and inversely proportional to the mass of the body. The larger the applied force, the greater the acceleration. The larger the body that a particular force is applied to, the less the acceleration of the body.
The fact that Sir Isaac’s first law of motion is the conservation of momentum with a consideration of momentum precludes that first law from being a law of motion in its own right. In classroom starkness, a law of motion that decides itself through exception is not going to be a law of motion in its own right.
The complicated part is there is a hidden or unstated entreaty within Sir Isaac’s first law. That unstated entreaty is the words of the first law are considered by mathematicians and physicists to explain a resistance to a change of momentum of a body. A mathematical physics student is expected to accept that, in the absence of an external force, the mass of an isolated body is what inherently forces that body not to have a spontaneous alteration of its momentum. And when an external force is applied, the resistance of the body to the change of momentum that the external force is causing is this force inherent to matter that is causing the body to experience uniform motion.
This quality of matter is labelled ‘inertia’ and sometimes Sir isaac first law is referred to as the law of inertia.
If it is accepted that the law of the conversation of momentum of collided objects can only be true if the momentum of a free travelling body is also perfectly conserved, it becomes apparent that a force called inertia emanating out of mass is an unnecessary add on. In fact it goes against Sir Isaac first rule of reasoning in philosophy which states “We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.” On top of that the concept runs awry of the idea of mass being and only being a scalar quantity. At school we teach that mass is measured by magnitude and magnitude alone. If a force resisting a change of motion was a quality of mass alone, mass would be a vector quantity. Force is measured by both magnitude and direction. At that level the unstated entreaty within Newton’s first law of motion becomes incoherent.
What is missing from Sir Isaac’s physics is the fact that a body's resistance to acceleration is born and only born when an external force is applied. And then that resistance force is simply explained by Sir Isaac Newton’s third law. That is the law that states that is an equal and opposite force to every force. If we look at the colliding billiard balls, the original stationary ball has not got a horizontal resistance to a change of motion. Simply because it is not subject to an opposite horizontal force. As the balls collide, its resistance to a change of motion in the horizontal plane is born as the equal and opposite force to the force to one causing the change. And the change of momentum of both balls is in accordance with Sir Isaac’s second law. Next we will have a look at the history behind Sir Isaac newton’s first law of motion and how it came to be a negative effect upon world history.
