2. Unit 3 Lesson 1 Kinetic and Potential Energy Indiana Standards Copyright © Houghton Mifflin Harcourt Publishing Company 6.1.4 Recognize that objects in motion have kinetic energy and objects at rest have potential energy. 6.1.5 Describe with examples that potential energy exists in several forms (gravitational potential energy, elastic potential energy, and chemical potential energy, among others). 6.1.6 Compare and contrast potential and kinetic energy and how they can be transformed within a system from one form to another.

3. Unit 3 Lesson 1 Kinetic and Potential Energy Indiana Standards Copyright © Houghton Mifflin Harcourt Publishing Company 6.4.3 Describe the transfer of energy amongst energy interactions.

4. Exciting Energy Copyright © Houghton Mifflin Harcourt Publishing Company What is energy? Energy is the ability to cause change. You use energy from foods to exercise, move, and even think. Nonliving objects also need energy to cause changes, such as movement or giving off light. Unit 3 Lesson 1 Kinetic and Potential Energy

5. What are two types of energy? Kinetic energy is the energy of motion. All moving objects have kinetic energy. The amount of kinetic energy an object has depends on mass and speed. The more mass or speed an object has, the more kinetic energy it has. Copyright © Houghton Mifflin Harcourt Publishing Company Unit 3 Lesson 1 Kinetic and Potential Energy

6. What are two types of energy? Potential energy is the stored energy an object has due to its position or chemical composition. Gravitational potential energy is caused by the pull of Earth’s gravity. All objects above the ground have gravitational potential energy.

7. What are two types of energy? Chemical potential energy results from the bonds between atoms. If chemical bonds are broken, changes can occur, releasing energy. Copyright © Houghton Mifflin Harcourt Publishing Company Unit 3 Lesson 1 Kinetic and Potential Energy

8. How are kinetic and potential energy different? Kinetic energy is the energy of motion, but potential energy is stored energy that can be converted into motion. Objects can have both kinetic and potential energy at the same time. Copyright © Houghton Mifflin Harcourt Publishing Company Unit 3 Lesson 1 Kinetic and Potential Energy

9. Add It Up! Copyright © Houghton Mifflin Harcourt Publishing Company What is mechanical energy? Mechanical energy is the combination of kinetic and potential energy. Mechanical energy is the sum of the motion and the position of an object. Unit 3 Lesson 1 Kinetic and Potential Energy

10. What is the law of conservation of energy? The law of conservation of energy states that energy can neither be created nor destroyed. It can only be transformed. If no energy is transformed, the mechanical energy of an object stays the same. Copyright © Houghton Mifflin Harcourt Publishing Company Unit 3 Lesson 1 Kinetic and Potential Energy
