Uncertainty principle (summary)

Heisenberg Uncertainty Principle or indeterminacy principle was given by German scientist Warner Heisenberg according to which position and momentum of an object can not be measured simultaneously. So if we measure the position of some particle more precisely then its momentum is measured less precisely and vice verse.

Lorentz Transformation

Derivation of Lorentz transformation equations using orthogonal transformations Let us consider two uniformly moving frames of reference where origins coincides at . 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 […]

Technothlon 2015 by IIT Guwahati

When it comes to testing the all-round development of a student, there are only a few sources from where a student can improve his internal material and grab a chance to examine himself on a national platform. The students of IIT Guwahati, however, have moved a step ahead and targeted at cultivating the basic analytical and comprehensive abilities of the children. Technothlon, an international school championship, is conducted every year as a part of Techniche, the annual Techno-management festival of IIT Guwahati.

Newton’s Third Law of motion (action-reaction and examples)

This article is about in-depth explanation of newton’s third law of motion. Here in this article I presume that you have a introduction of Newtons first law of motion and Newton’s second law of motion. Now Newtons first law and second law of motion deals with the effect of forces when they acts on a body. First law is about the change in the velocity of the body on the application of unbalanced forces and second law is gives the exact amount of the force needed to produce a given acceleration.

Circular Motion Physics : Detailed explanation

Circular motion is a very important concept in physics. Here in this page I would like to go through the concept of circular motion. You encounter circular motion in your day to day life. Many rides in amusement parks undergoes circular motion. Curves on highway are part of a circle and cars making a tun undergoes circular motion. Merry-go-Rounds in playgrounds offer further examples of uniform circular motion. Now let us learn more about circular motion.

How to solve electric force and field problems

This post is all about how you can easily solve electric force and electric field problems. At a glance problems of physics can seem to be scary and overwhelming for some students but do not worry all you need to do is your willingness to solve problem. So first of all you need to read your problem carefully and then start using following protocol to solve your problems. The procedure I am going to write is for calculating electric forces but you can use the same procedure to calculate an electric field by simply replacing the charge of interest, q, with a convenient test charge and dividing by the test charge at the end. So, to calculate the force,
