PHYSICS ESSAY HOW ELECTROSTATICS INFLUENCE OUR LIVES? INTRODUCTION We all are familiar with the term electricity which comes from batteries and which is used to light bulbs‚ buzzers‚ and other electrical devices. We also know that conductors are those objects which conduct electricity easily and insulators do not conduct electricity at all. This is basic knowledge but right now we are going into detail about electricity and static electricity. ELECTROSTATICS Many of us have this wrong concept

Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy
