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) »

Vector Questions

This page contains Vector questions for B.Sc. first year mechanics. You can also practice these questions if you are appearing for any after B.Sc. entrance exams(ex. IIT JAM) for pursuing M.Sc. Question 1 Define direction cosines of a vector. If  $l_1$, $m_1$, $n_1$ and $l_2$, $m_2$, $n_2$ are the direction cosines of two vectors show that the angle $\theta$ between them is given by $cos\theta … Continue reading Vector Questions »

Introduction to mechanics

So, what is mechanics? Mechanics we can say is an exact science. Again the question is what do I mean by an exact science. When we say that the physics or any branch of it is an exact science by this we mean that , its laws are expressed in the from of mathematical equations which describe and predict the results of precise quantitative measurements.
