Law 1. A body remains in its state of rest or in regular motion in a straight line, unless it is attacked by a force. Mathematically, we express the second law of motion as follows: The three laws of motion were first expounded by Isaac Newton in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687. [2] Newton used them to explain and study the motion of many physical objects and systems, laying the foundation for Newtonian mechanics. [3] In their original form, Newton`s laws of motion are not sufficient to characterize the motion of rigid bodies and deformable bodies. In 1750, Leonhard Euler introduced a generalization of Newton`s laws of motion for rigid bodies, called Euler`s laws of motion, which were later applied to deformable fields, which were assumed to be continuums. If a field is represented as a collection of discrete particles, each determined by Newton`s laws of motion, then Euler`s laws can be derived from Newton`s laws. However, Euler`s laws can be thought of as axioms describing the laws of motion for extended bodies independent of any particle structure. [20] Sir Isaac Newtown is widely recognized as one of the most important contributions to the field of physics. He is perhaps best known for the discovery of gravity. But perhaps his most important ideas are the concepts collectively known as Newton`s laws of motion or simply Newton`s laws.

To understand these laws, it makes sense to start with the basics. How many Newtonian laws are there and what are they? Newton`s 1st law states that a body at rest or in constant motion continues to be at rest or in constant motion until an external net force acts on it. Conceptually, Newton`s third law is seen when a person walks: you press against the ground, and the ground presses against the person. Similarly, a car`s tires press against the road, while the road pushes the tires back – the tires and the road press against each other at the same time. When swimming, a person interacts with water and pushes water back, while water pushes the person forward – the person and water press against each other. The reaction forces explain the movement in these examples. These forces depend on friction; For example, a person or car on ice may not be able to exert the force of action necessary to generate the required reaction force. [17] The ancient Greek philosopher Aristotle argued that all objects have a natural place in the universe: that heavy objects (like stones) wanted to rest on earth, and light objects like smoke wanted to rest in the sky and the stars wanted to stay in the sky. He thought that a body was in its natural state when it was at rest, and in order for the body to move in a straight line at a constant speed, an external agent constantly pushed it, otherwise it would stop moving. However, Galileo realized that a force is needed to change the speed of a body, but no force is needed to maintain its speed.

Galileo explained that a moving object will continue to move in the absence of a force. (The tendency of objects to resist changes in motion was what Johannes Kepler called inertia.) This idea was refined by Newton, who made it his first law, also known as the “law of inertia”: no force means no acceleration, and therefore the body will maintain its speed. Since Newton`s first law is a reformulation of the law of inertia that Galileo had already described, Newton gave Galileo the appropriate credit. Newton is perhaps best known for his work in studying the gravity and motion of planets. At the urging of astronomer Edmond Halley, after admitting that he had lost his proof of elliptical orbits a few years earlier, Newton published his laws in 1687 in his seminal work Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), in which he formalized the description of how massive bodies move under the influence of external forces. We can explain this to Naveen in terms of Newton`s first law of motion. The wallet moves forward with the car due to inertia until it is affected by another force, in this case the force of the car floor. These three laws form a basis for the study of the physics of motion and the forces involved.

There are linkages between these three statutes that become clearer as they are studied and applied. The correct application of Newton`s three laws provides solutions to problems and explanations for everyday phenomena as well as applications in engineering, architecture and technology.
