Life is essentially so interesting because it never ceases to change. But why does change seems different to different people? What governs their response to change?
If there is a better place than science to apply Newton's laws of motion, its life. For those who slept in physics classes let me quote the Newton's laws of motion and then I will explain my point of view about each of them.
1) First law of motion: Every body, moving or at rest remains to be so until an unbalanced external force is applied. This is also called the law of inertia. Inertia is a state of constancy and not necessarily idleness. It means the person has settled into a predictable life so comfortably that the life goes on for him without any change. The momentum of his life, large or small is always constant
For example, lets consider a vapid, unemotional but attractive young man who is the object of desire of a lot of girls. Some do try but he sis uninterested because he cannot reciprocate their feelings as he feels satisfied with himself and doesn't see a need for romantic interest. This is the effect of inertia, the need to change looks insignificant and the effort to change looks huge.
2) Second Law of motion: The rate of change of momentum is directly proportional to the net force applied. In other words, Force is something which can change the momentum. How potent the force is, is determined by the rate at which the momentum is changed.
Other than force, there is one other factor which governs the change in momentum: Inertia. Higher the inertia lower is the change in momentum. Extending the analogy of the young man, lets assume he is courted by a curious young girl incessantly. Slowly, young man becomes a lot more agreeable to the girl but she always complains him of being inattentive, inexpressive towards her. All the love she showers on the young man results in a slight smile or an invisible blush. The inertia of the young man against the force of love is huge and thus the momentum caused by love in general populace is hardly noticeable in our protagonist
Thus, force can change momentum to the extent inertia allows it
3) Finally, the most important law, the 3rd law: Every action has an equal and opposite reaction. This basically means that the force applied by an agent to change the state of target(opposed by its inertia), changes the state of agent himself(again opposed by his own inertia) as if the same force was acting upon the agent
Finally, When the girl proposes the young man for marriage, he becomes happy and says yes with his uneventful, hardly noticeable smile. While the girl is so happily chirping and blushing away to glory as if it was he who proposed her
The idea here is not to teach physics, but to teach life. I am sure I have been unsuccessful because everyone has their own views about life and this meager force can hardly challenge that inertia. I hope , though, I have been able to add a color to that kaleidoscope
Change is life's spice but everyone has his own tastes.
