Newton's Law Of Motion.

Newton's 1st Law Of Motion:
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

E.g.: A boy in love with a girl, continue to be in love with her and a girl in love with a boy, continue to be in love with him, until or unless any external agent(brother or father of the gal) comes into play and break the legs of the boy.



Newton's 2nd Law Of Motion:
The change in velocity (acceleration) with which an object moves is directly proportional to the magnitude of the force applied to the object and inversely proportional to the mass of the object.

E.g.: The rate of change of intensity of love of a girl towards a boy is directly proportional to the instantaneous bank balance of the boy and the direction of this love is same to as increment or decrement of the bank balance.


Newton's 3rd Law Of Motion:
For every action there is an equal and opposite reaction.

E.g.: The force applied while proposing a girl by a boy is equal and opposite to the force applied by the girl while slap.
