You need: Clean paper (2) / pencil Warm Up: Is FRICTION a force? Is GRAVITY a force? Support your answers. I CAN: define energy, give examples of different types, and define the law of conservation of energy.

2. To Do Today:
The teacher will give each student a Force Challenge (1-15 multiple choice).
You MAY use your notes, but not your neighbor. Circle your answer for each.
After finishing the challenge (15 min), you should be ready to move forward into new information – Forms of Energy.
Use the textbook to answer the four pages (on one paper) titled Forms of Energy.
Google Classroom has the same information – plus a video and a simulation.

3. Your first task is the Forces Challenge
Your first task is the Forces Challenge. Please put in your best efforts and circle the entire statement for the letter that you choose. You MAY use your notes – but not your neighbor!!
When you finish these four pages (1-17), move to the digital textbook for information on the types or forms of energy.

4. Forms of Energy Go to the internet and find this address:
You will be asked for a username: DPS7student
You will also be asked for a password: science1

5. Forms of Energy
Once you are “in” the textbook website, you will see an option for the “E-book” – click it.

6. Forms of Energy
Your next screen will likely look like this. Simply click on the textbook – the dogwood flowers.

7. Forms of Energy Find page 90 to get started.
Within the e-book, which is the digital textbook, you can turn pages – see the bottom center of screen.
Find page 90 to get started.

8. Forms of Energy
You have four pages of questions – all four on one paper – that are asking about this “lesson” within the chapter. Read through and find the answers. Please be sure to give GOOD answers – not scribbled mess. Give some real effort. I will be taking a quiz grade from at least one activity.

9. Forms of Energy
As you work on the worksheets, feel free to use the textbook – move through the pages of the chapter.
You may also click through the rest of this PowerPoint to find more info.

11. What is the difference between kinetic and potential energy?
The Nature of Energy
Energy = the ability to cause change.
Forms of energy include:
-Electrical -Thermal
-Chemical -Radiant

12. What is the difference between kinetic and potential energy?
Kinetic ENERGY
PotentialENERGY

13. What is the difference between kinetic and potential energy?
Kinetic ENERGY
PotentialENERGY
Mechanical Energy

14. What is the difference between kinetic and potential energy?
Kinetic Energy = Energy in the form of MOTION
Kinetic Energy (KE) depends on mass and velocity of the moving object.
Example of KE: Going down a slide

15. Reminder
Mass = the amount of stuff inside something…how much it weighs (while here on Earth) Velocity = speed AND direction…35 m/sec + East

16. What is the difference between kinetic and potential energy?
Potential Energy = Energy that is STORED
Example of PE: Waiting at the top of a slide

17. What is the difference between kinetic and potential energy?
Potential Energy = Energy that is STORED
Elastic Potential Energy = Energy stored by something that can stretch or compress.

18. What is the difference between kinetic and potential energy?
Potential Energy = Energy that is STORED
Chemical Potential Energy = energy stored in chemical bonds

19. What is the difference between kinetic and potential energy?
Potential Energy = Energy that is STORED
Gravitational Potential Energy = anything that can fall has stored GPE.

20. Question: what is the law of conservation of energy (and what does it mean)?
Answer: The law of conservation of energy simply states that energy cannot be created or destroyed…it will only transform from one type of energy to another. So whatever total amount of energy goes into a situation, the same amount will come out.

21. Law of conservation of energy
Light energy
Heat energy
Lightbulb (electrical energy)

22. Mechanical Energy Mechanical Energy = PE + KE
Mechanical Energy – total amount of kinetic energy and potential energy in a system.
Mechanical Energy = PE + KE
Point A: PE max, KE is 0
Point B: KE increasing, PE decreasing
Point C: KE decreasing, PE increasing
Point D: PE max, KE is 0
**Total mechanical energy**

23. Law of Conservation of Energy
No energy is lost, just changes form.
Law of Conservation of Energy
Law of Conservation of Energy = energy may change form, but it cannot be created or destroyed under ordinary conditions.
Friction converts mechanical energy into thermal energy.
Air resistance (a type of friction) converts mechanical energy into thermal energy
The breakfast you eat converts chemical energy into mechanical energy and heat energy so your muscles can help you pump your legs.
