WorksheetsReading 2 Part 1: Energy Pie Charts
Total questions: 10
Worksheet time: 6mins
Energy pie charts are
a way to show how energy is stored at different stages during a change.
qualitatively represent the energy stored in a system
a second tool used to help represent systems.
all of the above
Using energy pie charts eliminates the need to draw a system schema. The "system" is unimportant.
True
False
In general, you should include everything in a system that is involved in the CHANGE you observe in a system so that the total amount of energy stays the same (Law of Conservation of Energy).
True
False
Unless a system is specified to be frictionless, surfaces that may cause friction should be included in the system to capture all of the energy transformations that occur.
True
False
Energy storage modes include:
Energy stored in movement
Energy stored in position
Lost energy
Thermal waste energy
Eel represents
electric energy
elevated energy
elastic energy
According to the reading, kinetic energy is represented as
KE
EK
EngK
KinEn
Which statement(s) are true about what the reading calls, thermal waste energy?
It is abbreviated EthW
It is still stored in the system but is no longer usable; cannot be transferred back into another mode.
It is lost to the surroundings.
It is created when two surfaces rub against one another.
Eph represents
photo energy
phase energy
acidity energy
You may notice that the reading does not use the term 'potential' energy. What students typically consider 'potential' energy is most closely represented by the reading as:
Eph
EthW
Eg
Eth
