Sir Isaac Newton is one of the founding forefathers of modern physics. The three Laws of Motion by Isaac Newton published in “Philosophiæ Naturalis Principia Mathematica” published in 1687, are probably the most recognised pieces of his work and rightfully so, since they have formed the basis of half of what the modern principles of Physics are laid on before Albert Einstein’s work on Relativity. Sir Isaac Newton, a towering figure in the world of physics, laid the groundwork for understanding motion with his three laws of motion. This blog has been formulated by the top physics tutors in Kolkata from Mr. Banerjee Tutors’ Hub to help students understand complicated topics with ease.
Newton’s First Law – The Law of Inertia:
According to Newton’s First Law of Motion, any object at rest and an object in motion will continue to be those states respectively at a constant velocity unless an external force acts upon them.
This external force responsible for changing the velocity of a static or moving object is known as inertia. A reputable Physics tutor near me would often joke and tell his students that he would make use of inertia with a beating cane, whenever his students would act lazy or idle.
Newton’s Second Law – The Law of Acceleration
(Formula: F = ma (Force equals mass times acceleration)):
According to Newton’s Second Law of Motion, the acceleration of a body is directly proportional to the net force acting upon it and inversely proportional to its mass.
To put it simply, in order to get a lot of acceleration, one needs to apply a lot of force. Thus, the greater the force, the greater the acceleration.
Newton’s Third Law – The Law of Action and Reaction:
Probably the most famous and reiterated laws of Physics ever, the one your home tutor has repeated time and time again is Newton’s Third Law of Motion. It states that every action has its equal and opposite reaction.
This law emphasises the law of contact between two separate objects. When Object A applies force on Object B, following Newton’s third Law of Motion, Object B exerts the same amount of force in the opposite direction.
Conclusion:
Sir Isaac Newton’s Laws of Motion are one of the cornerstones of classical mechanics and one of the most influential Physical theories and laws apart from Albert Einstein’s Theory of Relativity. These laws provide deep insights into the fundamentals of the nature of motion, enlightening both professionals and laymen. Newton’s Three Laws of Motion are timeless principles that form the foundation of classical mechanics, providing insights into the fundamental nature of motion. From everyday experiences to complex scientific endeavours, these laws continue to shape our understanding of the physical world.
