In this second quiz on Energetics, we shall look deeply into some key aspects like; the various forms of energy, energy conversions, and the applications of energy in our day-to-day living. This is a very important aspect of physics that should be studied with a lot of concentration.
Energetics is a branch of physics that studies the various forms of energy, and their transformation. Real-life usage of energy can be seen as using the electrical energy stored in batteries to power and operate our electronic gadgets, and this energy must have been converted from another form (like solar energy). Another form of energy conversion could be the conversion of chemical energy stored in food, to mechanical energy when we exercise our bodies. So what is energy?
Energy is the ability or capacity to do work. There are many kinds of energy like solar energy, electrical energy, mechanical energy, nuclear energy, etc
