Click here to begin the activity. Energy Basics • Energy Is the Ability To Do Work Energy is in everything. We use energy for everything we do, from making a jump shot to baking cookies to sending astronauts into space. Energy comes in different forms • • • • • • • Heat (thermal) Light (radiant) Mechanical (motion) Electrical Chemical Nuclear energy sound Potential • Mechanical (motion) Electrical • Chemical • Nuclear energy Kinetic • Heat thermal •Light (radiant) •Mechanical (motion) Electrical Nuclear energy •sound There are two types of energy • Stored (potential) energy • Working (kinetic) energy • For example, the food you eat contains chemical energy, and your body stores this energy until you use it when you work or play Click your mouse to begin. •Decide whether each slide is an example of potential or kinetic energy. •Click on your answer to see if you are correct. Potential Energy Kinetic Energy Potential Energy Kinetic Energy Potential Energy Kinetic Energy Potential Energy Kinetic Energy Potential Energy Kinetic Energy Energy Sources • Energy sources are divided into two groups — renewable (an energy source that can be easily replenished) and nonrenewable (an energy source that we are using up and cannot recreate). • Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen Renewable energy sources include: • Solar energy from the sun, which can be turned into electricity and heat • Wind • Geothermal energy from heat inside the Earth • Biomass from plants, which includes firewood from trees, ethanol from corn, and biodiesel from vegetable oil • Hydropower from hydroturbines at a dam Alternative Energy Sources: • These renewable energy sources are sometimes called alternative energy sources • Solar • Water • Wind Nonrenewable Energy • We get most of our energy from nonrenewable energy sources, which include the fossil fuels — oil, natural gas, and coal. • They're called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth's core and pressure from rock and soil on the remains (or "fossils") of dead plants
