  1. Lesson 1 Reading Guide - Vocab Forms of Energy • mechanical energy • thermal energy • wave • sound energy • radiant energy • energy • potential energy • chemical energy • nuclear energy • kinetic energy • electric energy

  2. Lesson 1-1 Energy • Forms of Energy • A. Energy • 1. Energy influences everything in your life. • 2. Energy is the ability to cause change.

  3. Lesson 1-2 Potential Energy • B. Potential Energy • 1. Potential energy is stored energy due to the interaction between objectsand particles. • 2. Objects with potential energy have the possibility to cause change. • .

  4. Lesson 1-2 • 3. Any object has gravitational potential energy if it has mass and height aboveEarth’s surface.

  5. Lesson 1-2 Potential Energy(cont.) • 4. Chemical energy is energy that is stored in and released in thebonds between atoms. • Your body breaks chemical bonds in foods and coverts the released energy into other forms of energy that your body can use.

  6. Lesson 1-2 Potential Energy(cont.) • 5. Nuclear energy is the energy stored in and released from the nucleus of an atom. • a. The energy released from the Sun comes from nuclear fusion.

  7. b. During nuclear fusion, nuclei of atoms join together and release large amounts of energy. • c. During nuclear fission, the nucleus of an atom breaks apart, and energy is released. • d. Energy used in nuclear power plants to make electricity comes from nuclear fission.

  8. Lesson 1-3 Kinetic Energy • 1. Kinetic Energyis energy due to motion. • 2. The kinetic energy of a moving object is related to the mass and the speed of the object. • a. An object must have mass and speed to have kinetic energy. • b. If two objects have the same mass, the object that moves with greater speed has greater kinetic energy.

  9. 3. Electric energyis the energy in an electric current.

  10. Lesson 1-3 Kinetic Energy(cont.) How do potential energy and kinetic energy differ?

  11. Lesson 1-4 Combined Kinetic Energy and Potential Energy • D. Combined Kinetic Energy and Potential Energy • 1. A(n) system is a collection of interacting objects, parts, orideas that act together as a(n) whole. • 2. In science, the environment is anything that is not part of the system. • 3. The sum of the potential energy and the kinetic energy in a systemis mechanical energy.

  12. Lesson 1-4 Combined Kinetic Energy and Potential Energy (cont.) • 4. Thermal energyis the sum of the kinetic energy and the potential energy of the particles that make up an object.

  13. Lesson 1-4 Combined Kinetic Energy and Potential Energy (cont.) Compare mechanical energy and thermal energy.

  14. Lesson 1-4 Energy Carried by Waves • E. Energy Carried by Waves • 1. A(n) wave is a disturbance that transfers energy from one place to another without transferring matter. • 2. Sound energyis energy carried by sound waves, which are waves thatmove through matter.

  15. Lesson 1-4 • 3. Electromagnetic waves are electric and magnetic waves thatmove perpendicularly to one another.

  16. a. The energy carried by electromagnetic waves is radiant energy. • b. Electromagnetic waves travel through matter and alsothrough spaces with little or no matter. • c. Forms of electromagnetic waves include visible light, ultraviolet waves, X-rays,gamma rays, and infrared rays.

  17. Lesson 1-4 Visible light is one form of radiant energy.

  18. Lesson 1-4 Energy Carried by Waves(cont.) What two forms of energy are carried by waves?

  19. Lesson 1 - VS • Objects can have potential energy (stored energy) and kinetic energy (energy due to movement). • Mechanical energy is due to large-scale motions and interactions in a system. Thermal energy is due to atomic-scale motions and interactions in particles.

  20. Lesson 1 - VS • Two kinds of energy carried by waves are sound energy and radiant energy.

  21. Lesson 1 – LR1 Which term describes energy stored in and released from the bonds between atoms? A. chemical energy B. kinetic energy C. mechanical energy D. nuclear energy

  22. Lesson 1 – LR2 Which refers to a disturbance that transfers energy from one place to another without transferring matter? A. wave B. wavelength C. potential energy D. thermal energy

  23. Lesson 1 – LR3 What type of energy provides the warmth from the Sun? A. chemical energy B. nuclear energy C. potential energy D. radiant energy
