1. Starters for Week of Oct 12 – Oct 16 Name 6 simple machines10-14-15 W Name 2 classes of energy10-15-15 Th Calories per serving10-16-15 F – What does the number of Calories per serving indicate?

2. Forms of Energy

3. Ability to do work or cause change What is energy?

4. Energy… Produces Warmth Produces Light Produces Sound Produces Movement Produces Growth Powers Technology

5. How are energy, work, & power related? Work= transfer of energy Power = rate of energy transfer How can you judge how much power is involved?

6. POTENTIAL KINETIC Stored energy or energy of position Gravitational, Stored Mechanical, Nuclear, Chemical Energy of motion Motion, Electrical, Sound, Radiant, Thermal Classes of Energy

7. Kinetic Energy What factors affect an object’s kinetic energy? 1.Mass 2.Velocity

8. Potential Energy Stored energy that results from the position or shape of an object

9. Types of Potential Energy Gravitational Elastic

10. Potential energy related to an object’s height Any object that is “up high” Gravitational Potential Energy

11. The potential energy associated with objects that can be stretched or compressed. Elastic Potential Energy

12. Review Part 1 Energy is the ability to do work or cause change. 2 classes of energy: – Kinetic & potential Kinetic = energy of motion Potential= stored energy Factors affecting kinetic energy: mass & velocity

13. Review Part 2 2 types of Potential Energy: Gravitational & Elastic Gravitational depends on how high Elastic depends on an object being stretched/ compressed
