Number of independent coordinates that are required to describe the motion of a system is called degrees of freedom. In a system of N -particles, if there are k -equations of constraints, we have n 3N k number of independent coordinates. n degrees of freedom
Classical mechanics is the alternative to quantum mechanics. It is a branch of physics that describes the motion of macroscopic objects using principles established by Isaac Newton. Unlike quantum mechanics, classical mechanics assumes that objects have definite positions and velocities at all times.
The two divisions of mechanics are classical mechanics and quantum mechanics. Classical mechanics deals with macroscopic objects moving at speeds much slower than the speed of light, while quantum mechanics deals with the behavior of very small particles at the atomic and subatomic level.
Classical physics is often considered the opposite of quantum mechanics. Classical physics describes the behavior of macroscopic objects using classical laws such as Newton's laws of motion, while quantum mechanics describes the behavior of particles on a microscopic scale with wave-particle duality and uncertainty principles.
Classical mechanics was founded by Sir Isaac Newton in the 17th century with his work "Mathematical Principles of Natural Philosophy," also known as the Principia. Newton's laws of motion and the law of universal gravitation are fundamental concepts in classical mechanics.
The correspondence principle, articulated by Bohr in 1923, states that the behavior of quantum systems must reflect classical physics in the limit of large quantum numbers. This principle reconciles the differences between classical and quantum mechanics by showing that classical physics is a limiting case of quantum mechanics. It asserts that the predictions of quantum mechanics converge to classical physics predictions as the quantum numbers become large.
I think its three but not sure.

Classical mechanics is important because it provides the foundation for understanding the motion of objects and the underlying principles that govern their behavior. It allows us to predict how objects will move under various conditions, which is crucial for fields such as engineering and physics. Classical mechanics also forms the basis for more advanced branches of physics, such as quantum mechanics and relativity.
The two main branches are : 1) Classical Mechanics 2) Quantum Mechanics

Isaac Newton is considered the father of classical mechanics, as his work laid the foundation for understanding the motion of objects and the principles governing them.
Classical mechanics like in Abalone.Quantum Mechanics, such as in Gaussian.
Classical mechanics fails to accurately describe phenomena on very small scales, such as those in the quantum realm. Additionally, classical mechanics cannot explain certain phenomena related to high speeds or strong gravitational forces, leading to the development of theories like general relativity. Overall, classical mechanics is limited in its ability to describe the full range of physical phenomena observed in the universe.
The two divisions of mechanics are classical mechanics and quantum mechanics. Classical mechanics deals with macroscopic objects moving at speeds much slower than the speed of light, while quantum mechanics deals with the behavior of very small particles at the atomic and subatomic level.
the classification of mechanics are:- # Classical Mechanics # Statistical Mechanics # Quantum Mechanics
