Geo 2ei3 friday, september 9, 2016 module #2. What is energy and its different forms. What are the laws of the thermodynamics. Which forms of energy are predominantly used in our society. Sun is the most important energy for the earth"s system fuels climate, life support systems and cycling of matter. Energy reaching earth is only 1/50,000,000 of the sun"s output. Energy from sun governs relationships within organisms metabolism between organisms and organisms of the environment. Energy is the capacity to do work comes in many forms radiant energy, chemical bonds, heat, electrical, mechanical (potential stored energy or kinetic from motion or mass) Energy is different from matter does not occupy space and has no mass. Describe how energy transformations occur: first law law of conservation of energy. Energy can neither be created or destroyed it is changed from one form into another. Total amount of energy needed in the universe is constant.
