Degree of freedom Definition: – The minimum number of independent variables or coordinates required for specifying the position of a dynamical system consisting of one or more particle is called Degree of freedom. For the $N$ number of particles moving freely in $d$ dimensional space degrees of freedom is represented by the following equation. $f=Nd$ […]
Derivation of Lorentz transformation equations using orthogonal transformations Let us consider two uniformly moving frames of reference where origins coincides at $t=0$. let the source of light is fixed at unprimed frame of reference and emits a pulse of light. The observer fixed in the unprimed frame of reference will observe a spherical wave-front propagating […]

Question : Find out the total energy of earth in its circular orbit around the sun in terms of gravitational constant Answer: Let R be the total distance between the earth and the sun. If
If a particle falls from rest under the influence of gravity from higher to lower point in the minimum time, what is the curve that the particle will follow?
Suppose v is the speed of the particle along the curve, then in traversing ds portion of the curve time spent would be
