how can i get help in physics

From what has been discussed above, it may appear that if there were no friction, our life would have been much more easier and we would not have to spend energy in overcoming the frictional resistance. This is not true. As a matter of fact, it is only because of friction that we are able to move ..

Electric Charges and Field - The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated by simple experiment..

Introduction - You have learnt in the earlier chapters that flow of electrons constitutes an electric current and current can be generated from a battery or a generator. Scientists later discovered that there are many other ways of producing the stream of electron..

Based on dimensions, physical quantity can be classified under four categori..

There are 7 physical quantities viz., Length, mass, time, temperature, electric current, luminous intensity and amount of substance. Length, mass and time are called fundamental physical quantiti..

The other sciences like Biophysics, Geology, Heterology and Oceanography and Seismology use some of the laws of physics..
