# O level Physics quizzes on Energy quiz one

#### Quiz Description

Here in this physics quiz, we shall be diving into the study of energy which is one of the most important things to study as far as physics is concerned. We will get to look at the various forms of energy, their sources, and the transformation of these various forms of energy into other forms. If you are a physics student, this quiz is meant for you.

Energy is defined as the ability or capacity to do work. It can neither be created nor destroyed but can be only converted from one form to another (Law of conservation of energy). Some sources of energy are the sun (solar energy) which is the primary source of energy, wind power that comes from the wind, etc. As said earlier, energy can be transformed from one form to another, and any device that is able to transform any form of energy to another is known as a transducer. An example of a transducer is the human body. It converts chemical energy stored in food to mechanical energy during movement and physical activity.

As a physics student, you need to understand this topic as it is very vital in the study of physics. If you’re facing difficulties, don’t bother, this quiz is here to guide you. Good luck.
