This chapter considers energy as essential to life, but what is it and why is it so vital to living organisms? It is because energy is the basic constituent of the universe. The relationship between matter and its energy equivalent is defined by Albert Einstein’s famous equation E = mc2. This equation emphasizes that energy and matter are interconvertible as matter is condensed energy. The chapter defines energy as the capacity to do work, explaining that work is organized molecular motion that causes the displacement or movement of an object by the application of force and results in a specific physical change. Energy comes in many interconvertible forms: gravitational, nuclear, radiant, chemical, mechanical, electrical, and thermal.
