Classical Mechanics By Gupta Kumar Sharma Pdfl There are many different ways to explain the classical mechanics. In this essay, we will explain the classical mechanics by applying the mathematical differential equations of linear and angular motion. We will also discuss about Newton's second law of motion and importance of conservation laws. In summary, Classical Mechanics is a set of theories in physics that provide a mathematically based model for both particle motion and rigid bodies motion with constraints on physical objects in an inertial frame of reference moving according to a force applied at one or more points in space or time. The classical mechanics are based on the principles of classical physics, which dominated science before the development of quantum mechanics. Classical Mechanics deals with objects that are rigid beings (like mass phenomenons like moving fillings in teeth, actinides in atoms etc...) It is useful to make clear concepts of Classical Mechanics for any particle, body or static object in Physics. Also here we will use the term 'Classical Mechanics' to represent all theories that relate forces, accelerations and moments (like linear and angular momentum) through forces acting at various points in space and time. Classical mechanics explained these concepts with Newton's laws of motion. In modern times, it is best understood by the special theory of relativity as a limiting case of quantum mechanics. Classical mechanics is a term used to describe a branch of physics that first began to develop with Sir Isaac Newton's theories on motion and gravity. Newton's ideas were based upon his own laws of motion and the concept of mass conservation. His laws say that every object has an innate momentum. Also, if all objects are in motion, then there must be some outside force pushing them around, such as the wind pushing a box across the ground. Such objects do not have unlimited momentum and can be stopped if they hit another object with more momentum than theirs. Newton's second law says that the force acting on an object is dependent upon the mass of the object and its velocity. In other words, an object moving at a slower speed requires less force to accelerate it than a similar but faster moving object. This means that a feather would need a lot more force to be accelerated than a car. Newton's third law of motion basically stated that for every action there is an equal and opposite reaction. For example, if you push on a wall, then the wall pushes back with equal force. If you were to walk towards a wall, your feet would press against the ground and your head would be pushed away from the wall by Newton's third law of motion. Acceleration is the rate at which velocity changes. Velocity is the rate at which position changes. So, acceleration is simply the rate at which both velocity and position are changing at any given time.The essential problem in mechanics is to understand why objects move in particular manner whenever other conditions are fixed. It was Newton who developed a precise language for us to describe situations in terms of forces, masses and accelerations. The basic equation of motion for a particle was derived by Newton in his theories of dynamics. This equation says that force equals mass times acceleration . cfa1e77820
