This article is about Degree of freedom and constraints in classical mechanics. You can use this article for studying B.Sc, JAM , GATE and CSIR-NET Physics. Definition: – The minimum number of independent variables or co-ordinates required for specifying the position of a dynamical system consisting of one or more particle is called Degree of freedom.

This article covers topics like Law of conservation of energy, Equation of motion and Form of motion under the effect of central forces.
From equation 4 we consider \[f(r) = – \frac{{du(r)}}{{dr}}\] then this shows that \(f(r)\) is not only a central force but a conservative force. In this condition this equation

This article covers an introduction to central forces , equation of motion under central forces and
If the force \(\mathop f\limits^ \to \) acting on a body has following characteristics then it is a central force (i) it depends on the distance between two particles (ii) it is always directed towards or away from a fixed point. Gravitational force is an example of central forces. Mathematically if we consider central point as origin

This article is about matter waves and it contain brief introduction of the topic followed by few questions. Photoelectric effect and Compton scattering are evidences of the corpuscular nature of light. Interference , diffraction and polarisation reveal the wave nature of light. Louis de Brogli was the first one to suggest that matter may have
This article is about the revision of Particle properties of wave. I’ll be doing detailed articles on each one of the sub-topics given in this article. Classical Mechanics do not put any restriction on values of a dynamical property of a particle, so small and large both values are permitted. Principle of superposition:- When two
