Energy is _________________ • Energy moves cars along the road and boats over the water. • Energy bakes a cake in the oven and keep ice frozen in the freezer. • Energy plays our favorite songs and lights our homes. • Energy makes our bodies grow and allows our minds to think. What is Energy? • Scientists define energy as _______ _______________. In other words, energy produces change in something; it can do things for us. Where Does it Come From? • Some energy sources need to be taken out of the earth- this is called ____________________. – Ex: _____________________ ________________________ • Some energy sources need to be captured- this is called ____________________. – Ex: We can harness the motion of ________________ ___________ and convert this energy into electricity. We can also harness the __________ energy as heat. Forms of Energy • There are many forms of energy, such as light, heat, sound, and motion. However, all forms of energy can be put into two categories: 1.) __________ 2.) __________ Potential Energy • Potential energy is ____________ energy. • There are 4 main types of potential energy: – Chemical – Elastic – Nuclear – Gravitational Chemical Potential Energy • This is energy stored in the _________ of atoms and molecules. • Biomass, petroleum, natural gas, propane, and the foods we eat are examples of stored chemical energy. Elastic Potential Energy • This is energy stored in objects by applying a force. • Ex: When you squeeze or compress ___________ energy is being stored. • Ex: When you ___________ rubber bands energy is being stored. Nuclear Potential Energy • Energy stored in the nucleus of an atom; it is the energy that holds the nucleus together. • This energy can be released when the nuclei are combinedthis is called ____________. • This energy can be released when the nucleus is split apartthis is called _____________. • The sun combines hydrogen atoms to become helium- this produces nuclear energy through fusion. Gravitational Potential Energy • This is the energy of _____________ or place. • Ex: A rock resting at the top of a hill contains gravitational potential energy because of its position. • Hydropower, such as water in a reservoir behind a dam, has gravitational potential energy. Kinetic Energy • Kinetic energy is ______________; it is the motion of waves, electrons, atoms, molecules, substances, and objects. • There are 5 main types of kinetic energy: – Electrical – Radiant – Thermal – Motion – Sound Electrical Kinetic Energy • Electrical energy is the movement of __________. • Everything is made of tiny particles called atoms. • Atoms are made of even smaller particles called electrons, protons, and neutrons. • Electrons moving through a wire are called electricity. • ____________ is also electrical energy. Thermal Kinetic Energy • This is also called __________. • Thermal energy is the vibration and movement of atoms within a substance. • When atoms move, they bump into each other and create ____________, which produces heat. • The bigger and hotter an object is, the __________ thermal energy it has. Radiant Kinetic Energy • This is electromagnetic energy that travels in waves from the _______. • Radiant energy includes visible light, x-rays, gamma rays, radio waves and more. • All _______ we see then is considered kinetic energy. Motion Kinetic Energy • This is the movement of objects and substances from one place to another. • Objects move when an unbalanced _________ is applied to them. • ________ is an example of motion energy. Sound Kinetic Energy • This is the movement of energy through substances in waves. • Sound is produced when a force causes an object to ________________.
