Chastity : By the definition of British dictionary, "Chastity is the state of being chaste, it is also an abstention from sexual intercourse; virginity an celibacy". From religious prospective chastity is purity, " Chastity is sexual purity. Those who are chaste are morally clean in their thoughts, words, and actions. Chastity means not having any sexual relations before marriage. It also means complete fidelity to husband or wife during marriage."
Newton's First Law: Newton's first law of motion is often stated as "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acting upon an unbalanced force." " Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. The key point here is that if there is no net force resulting from unbalanced forces acting on an object (if all the external forces cancel each other out), then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. And if an additional external force is applied, the velocity will change because of the force".
