Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) "knowledge of nature", from φύσις phúsis "nature") is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.
We at E.S.A.W have developed products and equipments which help you to find and study elasticity of material, sound, wave, oscillations, optics, propetry of matter, motion, energy and many more natural activities that take place around us. So that childrens and people gain knowledge of the natural science taking place around us.
