![]() ![]() The principle of inertia is one of the fundamental principles in classical physics. The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to persevere in its present state, whether it be of rest or of moving uniformly forward in a right line. In his monumental Philosophiæ Naturalis Principia Mathematica, Isaac Newton defined inertia as a force:ĭEFINITION III. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed when no forces act upon them. This includes changes to the object's speed or direction of motion. The term inertia may also refer to the resistance of any physical object to a change in its velocity. The term inertia comes from the Latin word iners, meaning idle, sluggish. The modern use follows from some changes in Newton's original mechanics (as stated in the Principia) made by Euler, d'Alembert, and other Cartesians. Other, less forceful terms such as "to continue" or "to remain" are commonly found in modern textbooks. The word "perseveres" is a direct translation from Newton's Latin. Every object perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon. Īfter some other definitions, Newton states in his first law of motion: The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law of motion. an attempt to murder.Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. On the other hand, the same person may be penalized under section ‘IPC – 307’ a rigorous imprisonment for 7 years for just aiming a gun on somebody if his or her motive was to kill him i.e. Therefore, according to ‘Indian Penal Code’ a person is not to be penalized a death or life sentence under section ‘IPC – 302’ even if he or she had committed a murder but in self-defense. In English ‘Mansrea’ means ‘guilty mind’. According to law, the origin of Latin word ‘Crime’ is from a word ‘Mansrea’. This also explains why we always act in a certain manner or keep doing an act repetitively.Įven the premise of ‘Court of Justice’ is based upon it. not taking any action could be due to the inhibition or simply lack of interest in that particular act. Without a motive we do not take any action. According to this hypothesis, there is always a motive behind each and every act of a person. This is once again due to our motivation.Ī better explanation comes about the origin of word ‘Motivation’ from the word ‘Motive’. But this theory does not explain why we keep doing an act repetitively. This explains the fact that no movement takes place in us and we remain in state of inertia till our motivation forces us to do so. According to one hypothesis the word ‘Motivation’ has come from a Latin word ‘Motus’, which in English means movement. ![]() Without ‘Motivation’ nobody moves or does any thing. Now the question arises what is that force which forces us to change. This force could be due to our own will or could be the influence of someone else. We do not change our line of action either till the time a force compels us to change it. Most of the times, we do not take initiative or an action till we are compelled to do so. ![]() Similarly, we human beings do not change our state of affairs unless and until a force is applied on us. This external agency is known as a force. “Every body persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by force impressed on it”.Īccording to this law an object remains in state of inertia or in uniform motion till an external agency forces it to change its state. ![]() Newton’s First law of motivation (motion): But do we know these laws apply to human nature as accurately as it applies to Physics. We are aware of Newton’s laws of motion and its applications. Physics and human nature have lot many similarities. ![]()
