Galilean transformations

We can easily prove that Newton’s equations of motion, if they hold in any coordinate system, also hold in any other coordinate system translating uniformly w.r.t. the first frame of reference. This is the Newtonian principle of relativity. Galilean transformations are a set of equations which relate the space and time coordinates of two systems which are moving at a constant velocity relative to each … Continue reading Galilean transformations »

Spherical coordinates system (Spherical polar coordinates)

This article is about Spherical Polar co-ordinates and is aimed for First year physics students and also for those appearing for exams like JAM/GATE etc.
The spherical polar coordinates represent the coordinates of points on the surface of a sphere in a co-variant form. The coordinates of the point P in this system is represented by the radial vector r which is the distance from the origin to the point, the polar or

Coordinate transformation : translation, inclined and rotation

This article is about Coordinate transformation . In this article we will look at coordinate transformation in case of translation, inclination and rotation of S’ frame of reference with respect to S frame of reference. This article is mainly for B.Sc. first year and comes under subject Mechanics. Coordinate transformation If we define the position of a particle in two different frames of then in … Continue reading Coordinate transformation : translation, inclined and rotation »

Position of a particle (Mechanics)

This article ” Position of a particle ” is for B.Sc. students. We have also defined inertial and non inertial frame of reference in this article. Position of a particle (a) By Position Vector:- The line joining the point P and the origin ‘O’ of the frame of reference that is $\vec{PO}$ is known as position vector and is also represented by $\vec{r}$. (b) By … Continue reading Position of a particle (Mechanics) »
