I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Actually one of the easiest to explain and easiest to understand. Simply put, a body at rest tends to stay at rest, a body in motion tends to stay in motion unless an outside force is present to change that state. Closely related to Galileo's law of inertia, basically saying that if we, as people, are in motion, we tend to stay in motion. If we are at rest, we tend to stay at rest. Ever notice that the most successful people you know have a tendency to not sleep as much but always get the sleep they need? Or that they schedule themselves for just about everything? They know their time is precious and they use it wisely, time management being a very important part of their lives. If a person goes home from work, plops on the coach and watches TV till its time to go to bed, how successful do you think they will be?
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Simply put, the aforesaid object in motion, stays in motion along the same course (vector) as it was moving in. If you are moving in a positive direction, keep going. A body at rest requires the acceleration force to stop it from being at rest. If you were ever in the military, you know during basic training you learned a real simple version of this. If you werent moving in the direction or vector that the drill instructor wanted you to, he put a boot in your rear. That was the acceleration you needed to get on the right path. All of us at times require a little nudge to get us on the path that we need to be on and we have to get that force from somewhere, whether we do it from inside ourselves, whether an outside force exerts itself on us or what. Something has to exert a change in vector on us.
III. For every action there is an equal and opposite reaction.
The easiest to explain. For every effort or action you put out, you get a return action. And the greater action or effort, the greater return you get. If you make a point to smile at everyone you meet, that smile will be returned to you. If you put great effort into your business, that effort will be returned to you by the actions of others. As others see you putting that effort into everything you do, the greater will be the reaction that you are a person they want to follow. And they will want to send that effort back to you.
Obviously these laws are not intended to predict human behavior. There will always be an exception here and there. Maybe Newtons first law is acting on someone already so the third law doesn't have any effect. All of the laws are subject to outside forces and wont always predict the reaction you receive from others. But just maybe, if you follow the laws, and the next person you sign up sees you and the efforts you put out, maybe the second law will come into effect and you will be that force to create a new vector for them. And then they will do so, and then the people they sign will do so, and so on and so on. The reaction to your effort might end up coming back to you 30 fold.
