# Energy Study Guide

```Q1 Benchmark Study Guide
1. When you wrote your PB&amp;J procedure at the beginning of the year, what did you learn is important about writing a
procedure?
__________________________________________________________________________________________________
2. What is the difference between potential and kinetic energy?
__________________________________________________________________________________________________
Provide three examples of potential energy and three examples of kinetic energy.
Potential: __________________________________________________________________________________________
Kinetic: ____________________________________________________________________________________________
3. In the PORE lab when you dropped the marbles from two different heights, which height made the bigger impact?
Higher or shorter? Why did this happen? How does height affect an objects kinetic energy?
__________________________________________________________________________________________________
__________________________________________________________________________________________________
4. What are the three types of potential energy? Provide 3 examples of each type.
1. ____________________________, _______________________________________________________________
2. ____________________________, _______________________________________________________________
3. ____________________________, _______________________________________________________________
5. Where on a roller coaster can you find the most GPE? Where can you find the most KE?
__________________________________________________________________________________________________
6. The law of conservation of energy states:
__________________________________________________________________________________________________
7. List the 6 forms of energy and provide two examples of each type:
1. ____________________________, _______________________________________________________________
2. ____________________________, _______________________________________________________________
3. ____________________________, _______________________________________________________________
4. ____________________________, _______________________________________________________________
5. ____________________________, _______________________________________________________________
6. ____________________________, _______________________________________________________________
8. Describe the energy transformations that take place in the following scenarios:



Lighting a candle with a match: __________________________________________________________________
Rubbing your hands together for 20 seconds: ______________________________________________________
Honking a bike horn: __________________________________________________________________________
9. From your PORE: Hot &amp; Cold Water Part 1, explain why the red dye spread faster than the blue dye.
__________________________________________________________________________________________________
Hot substances have (more/less) thermal energy, therefore the particles move (faster/slower).
Cooler substances have (more/less) thermal energy, therefore the particles move (faster/slower).
10. Determine whether the motion of the molecules increase or decrease:



Hot coffee gets cold after sitting on teacher’s desk all day. _____________________
Leftover pizza warms up after 1:00 minute in the microwave. _____________________________
Water gets cold after adding ice cubes to it. _____________________________
11. What are the three types of heat transfer? Provide 2 examples of each type:
1. _________________________, __________________________________________________________________
2. _________________________, __________________________________________________________________
3. _________________________, __________________________________________________________________
12. Define the following terms:
Conductor: _________________________________________________________________________________________
Insulator: __________________________________________________________________________________________
13. Why are insulators important? What are some ways we use insulators in our lives?
__________________________________________________________________________________________________
14. Why are conductors important? What are some ways we use conductors in our lives?
__________________________________________________________________________________________________
15. In your PORE: Hot &amp; Cold Water Part 2, explain why the red dye did not mix with the blue dye when placed on top.
__________________________________________________________________________________________________
__________________________________________________________________________________________________
16. Explain what causes convection. In your explanation, make sure to include the term “density”.
