摘要

In physics, the concept of energyEnergy is not well defined. It is generally considered to be the capacityCapacity to do work. There are many different types of energyEnergy we deal with in physics. EnergyEnergy cannot be created or destroyed but it can be converted from one type of energyEnergy to another. We also know that energyEnergy and mass are related. This chapter focuses on the properties of energyEnergy. Some of the themes of the chapter are represented in Figs. 3.1, 3.2 and 3.3.
