1. Energy and Matter Chapter 6 Lesson 1 Mr. Nigh Science7

2. Kinetic and Potential Energy What type of energy represents a soccer ball flying through the air? It is moving, so it has Kinetic Energy It is in the air, so it has Potential Energy. Why? Because it is attracted to the Earth due to Gravity

3. Mechanical Energy is the sum of the potential and kinetic energy of a flying soccer ball or any other object Thermal energy is the sum of the potential and kinetic energy of the particles that make up a material. The particles that make up solids, liquids, and gasses are in constant motion so they have Kinetic energy.

7. Temperature Temperature is a measure of the average kinetic energy of the particles that make up a substance The slower the particles are moving, the lower the temperature The faster the particles are moving, the higher the temperature

8. Thermal Energy and Temperature If a frozen pond melts, both ice and very cold water are present. They have the same temperature. Thus, the particles that make up the ice and water have the same average kinetic energy However, they do not have the same thermal energy. The average distance between the particles that make up ice and water are different

10. What is Heat Heat is the movement of thermal energy from a warmer object to a colder object. All objects have thermal energy, however you heat something when thermal energy transfers from one object to another. Heat transfer from the cup to her hands is less than the transfer to the air, because the temperature difference is less

11. Thought Questions Lesson 1 The sum of kinetic energy and potential energy of the particles in a material is _____________ The difference between thermal energy and heat is _____________________ How could you increase the kinetic thermal energy of a liquid?
