Module 2 Energy in Society What this module is about Physics is a physical science, focusing on matter and energy. In biology and chemistry, energy is also discussed but to a very limited extent. It is in physics that we get a detailed information about energy. We should be aware of the important role of energy in our lives. Can you imagine what life would be like if there were no hydroelectric power plants and no geothermal power plants to generate electricity? Do you think we could reach distant places if crude oil was not introduced in the market? We learned how to harness energy for our benefit. What do you think are the benefits that we get from energy? While energy is very beneficial to us, we must not forget that it can also cause harm. What do you think are the bad effects of energy on the environment? How do you explain the idea that the total mass-energy in the universe is constant? Reading and doing the activities in Module 2 could answer all these queries. Enjoy reading!
