CENTRE OF MASS, LINEAR MOMENTUM AND IMPULSE.
Here we are going to have a look on important topics of mechanics. We start with centre of mass. As we all know every matter has mass and gravity acts on them. Then we assume that gravitational force acts on a point of body at...
Know About Atomic models !!
As we know, matter is made of atoms. Here, we are going to know further more things on atoms. Atoms are made of further small constituent particles like electrons etc. The first atomic model is proposed by J. J. Thomson in...
All About Learnpedia.
Learnpedia is an edu-tech company that promises to make learning a fun and fascinating experience for students preparing to write various competitive exams. Its flagship product ScoreJEE is already redefining preparation for...
Wave Motion
Here we’ll look for mechanical waves-transverse and longitudinal waves. In transverse wave particles oscillate in perpendicular to direction of wave propagation and in longitudinal they oscillate in parallel with wave...
SIMPLE HARMONIC MOTION
We know that oscillations are the motions which repeat themselves again and again. Simple harmonic motion is also type of oscillations which can be written as equation in form of sine or cosine form. They are also called...
MAGNETIC EFFECT OF CURRENT AND MAGNETISM
First of all magnetic field lines are produced from magnetic pole and ends on it. These lines form closed loop. Charge moving in magnetic field experiences force which is dependent of velocity of charged particle. Its direction...
PHYSICS OF NUCLEI
Here we’ll have a look on nucleus of atom. It is consisted of nucleons i.e. protons and neutrons. Before that you should know about atomic mass and its units which we study in chemistry. Atomic mass of atom is approx. equal...
TUTORING PHYSICS HAS ALWAYS REQUIRED A SPECIAL ABILITY
Physics is the basis of many other sciences like chemistry, astronomy, and biochemistry. Physics is an interesting subject that can improve your problem solving and analytical skills. Online Physics tutor is a part of our daily...
The Basics to Chemical Kinetics and Its Applications
Reaction kinetics measures how quick a reaction occurs. Collisions form the basis for chemical reaction to occur. A collision needs to be of sufficient energy if the necessary bonds are to be broken. This forms the basis of...
