1 Title of notes: Energy p. 25 & 26 RS

2 Pick a science word and write the definition. Chapter 17
Bell work - 3 minutes Pick a science word and write the definition. Chapter 17

3 I can describe what energy is.
Learning target I can describe what energy is. Today I am… learning about types of energy. So that I’ll be able to… understand how fossil fuels are used. I’ll know I’ve got it when… I can write at least one sentence explaining what energy is and the two types of energy possibilities.

4 Energy is the ability to do work.
What is Energy? Energy is the ability to do work.

5 Potential energy is stored energy.
What is Energy? Potential energy is stored energy.

6 Kinetic energy is energy in motion.
What is Energy? Kinetic energy is energy in motion.

7 Mechanical: Associated with the motion and position of an object.
Forms of energy Mechanical: Associated with the motion and position of an object. Example: A baseball has mechanical energy that is kinetic

8 Electrical: Associated with electrical charges.
Forms of energy Electrical: Associated with electrical charges. Example: A cell phone battery is potential electrical energy. Making a call the energy is changed to kinetic electrical energy.

9 Thermal: Associated with the heat due to particle movement
Forms of energy Thermal: Associated with the heat due to particle movement Example: The particles in hot volcanic lava move very fast.

10 Electromagnetic: Associated with the movement of waves.
Forms of energy Electromagnetic: Associated with the movement of waves. Example: The sun warming you is electromagnetic waves.

11 Forms of energy Chemical: Associated with the chemical bonds. When bonds break energy is released. Example: The food you eat provides your body with chemical energy (potential).

12 Nuclear: Associated with the forces within atoms.
Forms of energy Nuclear: Associated with the forces within atoms. Example: The forces that hold nuclear particles together in the nucleus can store potential energy.

13 Can energy change from one form to another
Can energy change from one form to another? Write down 2 examples in your notes. * Turning on an electric fan. Electrical E  Mechanical E (Fan Blades Spinning) * Fireworks exploding Chemical E  Thermal E (Heat) & Electromagnetic E (Light) * Combustion Chemical E (Stored in fuel)  Thermal E (Heat) & Electromagnetic E (Light) * Electricity Chemical E (Burning Coal)  Electric E

14 Sources of Energy Energy resources are divided into two categories:
Renewable Energy - Sun - Wind - Moving Water Wood - Geothermal Nonrenewable Energy - Coal - Oil - Natural Gas - Nuclear Energy

15 Forces that act on objects
Applied force: An applied force is a force that is applied to an object by a person or another object. Gravity force: The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. Friction Force: The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. Normal Force: The normal force is the support force exerted upon an object that is in contact with another stable object.

16 Bullet points those facts
Pg Write down two facts from the reading. Choose facts that we did not talk about during lecture. Bullet points those facts

17 Potential and Kinetic Energy pg. 25 LS
Draw a picture of potential and kinetic energy Label each type in the picture or draw two separate pictures Must have color
