Introduction

This course covers some basic principles of Physics and describes them through few simple experiments. Sometimes the phenomena is shown first, then in order to understand and analyze it, the theory is explained. In some cases it is the reverse.
The discussion is roughly at +2 and UG first year level but the experiments could be an educative experience for students from grade 9 onwards. Most of these experiments throw some challenge to understand it, so even the well trained persons up to Postgraduate level will find it interesting!

Core target groups are

Physics teachers teaching in schools from grade 9 to 12

Physics teachers teaching in colleges at B Sc, B.Tech level

Students from grade 9 to BSc/B.Tech

Others interested in enjoying Physics displayed by Nature in day-to-day life
