Multiple Choice
Claim A: More potential energy can be stored by moving against the magnetic force of a stronger magnet.
Which test result provides the BEST evidence for evaluating Claim A?
Moving two weak magnets together stored the most potential energy because they were easier to push.
Moving two strong magnets together required more force, showing that more potential energy was being stored in the field.
Letting magnets move freely without pushing them stores energy in the field.
D. Changing the distance between weak magnets changed the field strength the most.

Multiple Choice
Which result from the Magnetic Force simulation BEST supports Claim B: Magnetic forces are stronger in certain parts of a magnetic field?
The force was the same everywhere around the magnet, no matter where objects were placed.
The force increased as objects were placed closer to the magnet and decreased when they were farther away.
The force only appeared when two magnets were pressed directly together.
The sensors only detected force when the magnet was rotated.

20
Multiple Select
Select all statements that are supported by the evidence shown in the simulation and repelling magnets cards.
The force between magnets increases as they get closer.
It is easier to push magnets together when they are far apart.

24
Multiple Choice
What happens when you move a magnet against a stronger magnetic force?
It transfers less energy to the magnetic field.
It transfers more energy to the magnetic field.
It does not transfer any energy to the magnetic field.
It destroys the magnetic field.

Multiple Choice
Based on the data shown, what is the relationship between the distance before launch and the speed after launch for the spacecraft?
The greater the distance before launch, the higher the speed after launch.
The shorter the distance before launch, the higher the speed after launch.
There is no relationship between distance before launch and speed after launch.
The speed after launch is always the same regardless of distance.

Multiple Select
Which of the two following claims best explains why the spacecraft went faster than expected on Wednesday?
The magnets were weaker on Wednesday.
The magnetic force was much stronger on Wednesday because the magnets were stronger.
The magnetic force was much stronger on Wednesday because the magnetic force is stronger closer to the magnets.
The spacecraft was lighter on Wednesday.
