The law of conservation of energy states:
It is important for any civilization to conserve its energy.
Energy that is not actively conserved will be lost forever.
Energy cannot be created or destroyed, only transformed.
Describe your energy at the top of a roller coaster hill, just before you start moving into the big drop. You are currently perfectly still (aside from the screaming).
Because you aren't moving, you have no energy.
You have potential energy.
You have kinetic energy.
You have both kinetic energy and potential energy.
I stretch a rubberband and fling it at across the room. When does the rubber band have energy?
Only when its flying across the room.
Only when it was stretched tight.
Both when its stretched tight and when its flying across the room.
There is not enough information to answer this question.
Where does electricity in your house come from (the type that comes on when you flip a switch)?
Coal and oil are burned to heat up wires, which makes energy flow through wires.
Humans mine rocks that are naturally magnetic and electric. These are made into large batteries.
Humans heat up water and create steam in order to spin magnets near wires.
Earth's magnetic field is used to create electricity.
No one knows for sure where electricity comes from.
Energy is neither _________ nor _________ but can be _________ from one form to another
Created, destroyed, transferred
Transferred, created, destroyed
As a pendulum swings from its highest to lowest position, what happens to its kinetic and potential energy?
The PE and KE increase and decrease together
The PE decreases while the KE increases
Impossible to know without knowing the mass
According to the Law of Conservation of energy, the amount of energy before and after a reaction must be the same. Which statement below is true?
The total amount of energy is conserved
The total amount of energy is more after a reaction
The total amount of energy is less after a reaction
As an object falls from the top of a high building, describe its kinetic and potential energy over time.
Both increase
Both decrease
Kinetic energy decreases and potential energy increases
. Kinetic energy increases and potential energy decreases
The law of conservation of energy is a statement that
Energy must be conserved and you are breaking a law if you waste energy.
the supply of energy is limited so we must conserve.
The total amount of energy is constant.
energy cannot be used faster than it is created.
The law of conservation of energy says what about the energy in a system?
It never changes
It gradually decreases
It gradually builds up
It's sporadic depending on what is happening in the system
What is the ability to do work?
Matter
Motive
Energy
Atoms
_________________________ says that energy is not created or lost, it just changes forms.
