Physics IN OUR DAILY LIVES “Any sort of technology which we uses IN our daily life is related to Physics.” Physics is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will
