The different forms of energy Notes-feb. 7

What forms can energy take? Unit 2 Lesson 1 Introduction to Energy (page 100-110) What forms can energy take? Mechanical energy is the sum of an object’s kinetic energy and potential energy. It is the energy of position and motion. Sound energy is kinetic energy caused by the vibration of particles in a medium such as steel, water, or air.

What forms can energy take? Unit 2 Lesson 1 Introduction to Energy (page 100-110) What forms can energy take? Electromagnetic energy is transmitted through space in the form of electromagnetic waves. These waves are caused by the vibration of electrically charged particles. Electromagnetic waves include visible light, X-rays, and microwaves.

What forms can energy take? Unit 2 Lesson 1 Introduction to Energy (page 100-110) What forms can energy take? Electrical energy is the energy that results from the position or motion of charged particles. Chemical energy is a form of potential energy. The amount of chemical energy in a molecule depends on the kinds of atoms and their arrangement. Copyright © Houghton Mifflin Harcourt Publishing Company

What forms can energy take? Unit 2 Lesson 1 Introduction to Energy (page 100-110) What forms can energy take? The thermal energy of an object is the kinetic energy of its particles. The faster the molecules in an object move, and the more particles the object has, the more thermal energy it has. Heat is the energy transferred from an object at a higher temperature to an object at a lower temperature. Copyright © Houghton Mifflin Harcourt Publishing Company

What forms can energy take? Unit 2 Lesson 1 Introduction to Energy (100-110) What forms can energy take? The nucleus of an atom is the source of nuclear energy. When an atom’s nucleus breaks apart, or when the nuclei of two small atoms join together, energy is released. Copyright © Houghton Mifflin Harcourt Publishing Company
