### Ch.7 Introduction to Work,Energy,and Energy Resources

Energy is characterized by its many forms and the fact that it is conserved.We can loosely define energy as the ability to do work,admitting that in some circumstances not all energy is available to do work.Because of the association of energy with work,we begin the chapter with a discussion of work.CHAPTER 7 RED-SHIFTS AND ENERGY BALANCECHAPTER 7 RED-SHIFTS AND ENERGY BALANCE Red-shifts Energy density of radiation Energy density of matter Continuous creation Religion teaches us that matter in all its forms,including ourselves,is created and did not evolve from natural processes.Natural science,on the other hand,claims theCHAPTER 7 RED-SHIFTS AND ENERGY BALANCECHAPTER 7 RED-SHIFTS AND ENERGY BALANCE Red-shifts Energy density of radiation Energy density of matter Continuous creation Religion teaches us that matter in all its forms,including ourselves,is created and did not evolve from natural processes.Natural science,on the other hand,claims the
