The word 'Physics' comes from the Greek word 'phusis' meaning 'nature', introduced by the ancient scientist 'Aristotle'. Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is de..

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..

International System of (SI) unit has been adopted for measurement by scientists all over the world. Three fundamental units needed in physics are those of lengths, mass and time. Units of all other physical quantities we come across in physics are de..

Most experiments in physics require the observations made to be quantitative rather than qualitative. If observations are only descriptive or qualitative, they are likely to be imprecise and could cause disagreements between experimenters. For example, scientists cannot merely ..

Power - A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is done, that is..

In no subject does measurement play as important a role as in science. Real science cannot exist without measurement. According to Lord Kelvin, one of the greatest scientists, unless you can measure what you are speaking about and express it in numbers you have not started 'Exact Science'..

Estimation by orders of Magnitude of size (Length, Area and Volume) Mass, Time - In no subject does measurement play as important a role as in science. Real science cannot exist without measurement. According to Lord Kelvin, one of the greatest scientists, unless you can measure what you ..
